Scanned and road tested. Refused to do anything else. Spoke to a regional rep who just stonewalled. They did not take it back. The original selling dealer wanted to find away out of this and bought it from me. I am not nearly as knowledgeable as you guys. Was afraid to drive the car.

Btw what kind of car was this?
So you diagnosed it at 1 dealer and then the original dealer did a buy back?

This happened twice about 6 months apart. 2009 Db 9 manual. Bought in NY. In florida now where it happened again. Dealer herE could not replicate the problem after driving. No surprise since it happened twice in 6 months. The first time I thought it was just a fluke. They were not willing to do anything further. When I spoke with the AM NY rep he asked lots of questions that indicated to me that he know of the problem, but after I responded, wanted nothing further to do with the issue.

I'm not saying all ppl but their is a large number of clients that believe the technician is a magical magician, what they forget us without the right information nothing will get resolved..example:
Client: "My stick shift car stalled on me once a months ago, what's wrong?"
Tech: he scans car and notices no faults, he drives the car 5 miles with no issues...car is leased to client and tech will just assume client just doesn't know how to drive a stick shift.....why waste more time on this car with nothing to go on at present time?
You see, until something is seen or simulated, the tech cannot do anything further. The tech is paid upon work he corrects under warranty or client pays to carry out..aka time is money( unpaid time comes off the techs weekly paycheck). The tech can spent countless hours on your car repairing but if he doesn't simulate a concern to repair, then any further time he spends after the no fault road test will not be paid. So that car gets kicked outside and onto the next...sad but true, so EVERY information point helps get your car fixed on intermittent problems.
If the car stalled 2 times in a 6 mth period, then your obviously aware it's very intermittent...did you ever road test the car with the tech riding shot gun? Did you work with the dealer to help them try and simulate the concern?

Sorry if I was not clear. The questions came from an AM regional manager. I responded and he would not pursue. I offered to leave the car with the repair shop as long as they wanted to keep it. They were unwilling to do anything further and insisted that I take it out. Seems to me that experienced people can look for root causes of problems that they have evidently heard of previously. I had an extended warrantee on the car. Don't really know what else I could have done.

Well, After multiple times trying to fix an underway engine stalling problem, AM is still baffled. ('09 6-spd, sports pkg, convt, 2500 miles) My car has been in the AM shop more than in my garage over the past 2 months and they can't seem to fix the problem. It simply stalls out when slowing to a stop at lights, turns, etc. No drama, shuddering, noise or anything else. The engine simply drops straight down to 0 rpm and dies quietly. Every time it starts right back up and it doesn't do it every time. Yet, it has scared the hell out of me a few times, when it puts me in an unsafe situation with following or approaching traffic. The AM tech's and Zone Aftermarket Sales Rep have driven the car extensively and have experienced the problem themselves. Yet, each time they return it, they say they haven't seen the stall for a while, so assume it must be alleviated.
They've reflashed the computers any number of times, replaced the mass air flow sensor, fuel pump and key (ECU) slot. The computer apparently does not throw a code and their techs reported being as baffeled as I am. They have gone back to the UK with info frequently, but no firm fix has been developed yet. Each time I get it back, after some days of driving, it will just decide to stall in awkward spots. Now, I watch the tach like a hawk to immediately respond. I've learned the response routine well...quickly hit the emergency flashers, wave my arms over my head to warn those behind me (when top is down) and quickly come to full stop, step back on clutch in neutral, pop out the key, reinsert key and start her back up as quickly as I can. Several times the folks behind me nearly smacked me, fully expecting me to move on or make a turn quickly. I'm getting tired of the horns and nasty hand gestures!
I've now documented my major discontent and safety concerns to AM (everything is very well documented) and am waiting their response. I've usually been lucky with cars, but as someone here previosuly said, "...can you say lemon..."!

I have had mine stall for no reason in traffic before. I F***ing hate the stupid ECU key at that moment, having to remove and reinsert the thing is ridiculous. Feels like an eternity even though it isn't, and embarrassing. Fortunately I believe mine was driver error.

So glad they bought mine back without hassle. I moved on to a DBS at the time and it was great, but now long gone. I seem to recall AM found some type of split/leak/failure in a fuel pickup hose from or in the fuel tank, that caused the unusual stalling. Not sure of that, though. I've moved on to many other manufacturer's since back then.

I'm a BMW technician, but have a 4.7 GT (also 6spd manual).
The issue is indeed a fueling problem. The check valve that's integrated into the fuel tank vent line (Part # 4G43-9B035-AB) is the most likely cause of this. Richard (Redpants) has done a fantastic video outlining the additional symptoms that he was facing. The only symptom I ever had was the intermittent stalling when coming to a stop after "spirited" driving. This would occur 2-3 times a day; but it's also worth noting that it's rare the engine is ever below 4500rpm. These plastic hoses time out, and in my option should be replaced every 10 or so years. After replacement, my symptoms never returned.

Thank you, I will check it out. When mine has stalled out a few times, I believe it was user error, my fault. I have a 6 spd Coyote Mustang and it is a dream to drive and never ever stalls. You can creep along in traffic, just lift the clutch and the car drives forward, barely need to use the throttle. The Vantage will die doing the same unless you give it throttle. Most aggravating in my opinion is the ECU key to restart, pushing in and out, being careful not the let it pop out and fall on the floor.
The time it takes to start/restart the car is hands down the most annoying qualm I have about the Aston.

It very well could. I know one of Velocity AP's post mentioned that fuel level made a difference and I could see it affecting the hose, as when there is a fair amount of fuel in the tank, these lines/check valve are submerged. It's performance may differ when non-submerged, but I couldn't say for sure.
