Intermitent no spark
1991 A4
Will start and run for about 30 minutes, then stalls with no restart, im getting no spark. If left over night or for a few hours it will restart and run for an unknown period of time. This happens whether just idling in the garage or driving at any speed.
So far-
Replaced cap and coil
ran for a few hours and thought problem was fixed but to my avail it stalled again, restarted for about 3 minutes and then stalled for good, no spark, until the next morning at which time it ran for another hour and stalled.
Getting over 7 volts at dist. Battery terminal
Can anyone help me find a place to start? Could this be an ECM problem?
Thanks

It sounds like an (ignition control module) to me , this can cause intermittent starting and dying. I believe these can be tested,new ones run about $50.00...WW

Lucky you got a warning. When my ICM died suddenly, it took my coil out with it! Flat-bedded me like a ****!

well my cap and coil were shot when the problem arose, the coil was arcing all over the place and the cap was in rough shape so i think they all went at the same time.
200 miles and still running strong, im a happy camper. Cant believe i let the car sit for six months because of a 40 dollar part.
thanks again
