If the car runs, then shuts off, I'd check the soldering
DDillenger, I'll do that. But, wouldn't the car simply not start if there were a solder issue?? Also, what about how I need to disconnect the ECU, I suppose to allow caps to discharge, before it will start again. ( If I leave the ECU in the car, after the engine dies, i cannot restart the car.)
I'll do what you said, because you are always right and your advice has always panned out for me.
Thank you for your attention to my problem/s
