I need some help. I have never had ANY issues with this car, but have a confounding one currently.

2.5 weeks ago I drove from Daytona area to Orlando to drop my car off for some dent repair, minor paint work, paint correction, ceramic coating, etc. (guy did a fantastic job and really knows his cars).
My car is an EVT775 car with tune from Rob Harper (Robtuned). It runs E85 through ID 1300 injectors. I was getting close to running out of fuel and and found a Sonoco Station with 'Pure Power E85 R'. Filled up, made it to the paint guy and dropped the car off.
As the work is nearing completion he calls me to tell me that the car started but then died. Started up again, ran for 3-4 minutes and then shut off. Can't start the car again unless you disconnect battery or let it sit for 20mins to an hour.

I went over yesterday with my other key, just to rule that out and we get the same result.
I often let my car sit for 2-3 or more weeks at a time with E85 in it and it starts up fine. So the only thing that's different is this E85R.
They did remove the front bumper. But we went back again and checked grounds and everything looks good.

Has anybody experienced an issue like this before? Car starts perfect, warms up, then shuts off on its own and won't restart. They did also check for power to the fuel pump. On initial start up the fuel pump gets power, after the car shuts off no power gets to the fuel pump.


Also, it does not throw ANY codes............Aaarrgghhhh

 

So you disconnect the battery and you can restart it immediately? That is interesting. Have you had a chance to log some values while it's running as it dies? Have you driven it after starting and the 1 minute or so wait and does it die while driving?

I always ask "What changed?" In this case, it sounds like gas. You might want to contact the station or whatever agency controls fuel in your State to see if they have any reports of problems.

You might want to get all that gas out and get some good known gas you have used before in it to see if that has any effect.

It sounds like something is screwing with the ECU pretty hard and cutting off fuel to the engine. I am not knowledgeable enough to even guess where to start, but fuel and logging values comes to mind.

Working on putting it on a flatbed to bring it back home so I can check some things. The guys who did the work on it also thing that gas might be the culprit. But when you start it initially the car runs great, until it warms up and then it shuts off.

 

Just for kicks, yank both MAF connections to see if anything changes.
