Does the tach drop to zero when the engine quits?
If so, that would suggest it's ignition, not fuel related.


In reading your post, I'm surprised there isn't a flag when reading the codes. There can be active codes, either a F or f, but the dealer diagnostic should be able to go deeper and check for the history, which can reveal codes not visible when doing a general scan. My Xentry setup gets me access.


It's not unknown in the older cars to have the ignition switch cause this same problem. I wonder.........
