Re: car starts and run for 15-20mins then cuts off
I presume the car is an IROC based on your userID. Sounds like whateve it is, the problem occurrs when the car enters closed-loop mode.
Is the check engine light comming on? Have any of the 3 shops managed to extract error codes from the ECM - if so what are they? Does the car shutter and cough after 15-20 minutes, or just shut down as if the key was turned off?
Give us a little more info on the car like the year, engine size, when did this problem start, etc.
