I'm glad you're all so smart. I just picked up my car from the local repair shop and I gave them the comments you all posted. Sure enough, the purge valve in the vapor line was the issue. So, for now they've unplugged and capped the vapor line as they can't find the ball that's supposed to keep the gas out of the line.
They said it's bound to cause a check engine light but I can at least personally take it to the dealership now vs paying to have it towed.
My local shop didn't want to try to find/fix the ball as there's a lot of things going on between the engine and the gas tank they're not experienced with.
Thank you for helping me solve the mystery.

This ball your talking about is more like the rubber purge hose supply lines in the tank, small hoses failed and are coming apart..hose will need to be replaced and possibly the purge valve along with the DMTL pump assembly depending on the amount of fuel that was sucked through..If you have fuel saturated in the DMTL, this can cause a fire..electric coil closes the canister vent (DMTL valve)..vapours of fuel is what the coil is made for, not to be saturated in fuel...

"With a Cold Engine" ..Start vehicle, select neutral..let idle for 10 seconds..you will hear a click beneith vehicle..clutch relearn has completed. if heavey use has been done on clutch since last shut down (track racing..etc then engine was shut off) ..up to 3 relearns can be required, to do so ignition will need to be cycled off between each relearn..
Yes it will do wonders on driving and on clutch operations/feel..also will help minimize the slippage of the clutch which will prolong clutch life (clutch life also depends on driving behavior)..[/quote]
Is this procedure to be used with a Manual Clutch Also?

No. This is for SportShift cars only. There is no sensor in a manual car to read the clutch position.

Same problem...
Driving down road my 07 V8 Vantage will suddenly loose throttle and a half second later throttle comes back. It might do it every second for several seconds or once in 5 minutes. It does not matter what speed I'm going, what gear I'm in, the temperature of the engine nor RPM. If I'm sitting at a stop light when it decides to act up the car will die.
My service was not able to pin point the source yet but they did tell me to monitor if it happens with empty or full tank. I guess they are suspecting the tank issue mentioned here...
