OMG!!! That was IT!!!!
I disconnected the one ignition module and the car now stays running!
I've been trying to figure this out for a month!
Thanks so much guys.....do I need to replace the coils too or just the ignition module?
At this point maybe I should just swap out both modules and coils to be safe.
What do you think?
Thanks again,
Don

" I similarly did this test without knowing what it would tell me. In my case, it ran poorly on either module. I guess if it ran flawlessly on one, you’d know you needed to replace the other coil / plugs / wires ? "
__________________ What I ended up doing on my car was swapping out the ing module as I plugged in the wire from the module from suspect bad system and the car ran great showing my that the coils wires caps etc. were in good condition and I just need the module was like 25 American so I have an extra

It could any one of many elements in the problem system, e.g. spark plugs, wires, cap, rotor, coil, or ignition module.
Don't waste money buying unnecessary parts, e.g. ignition coils.

I never tried switching the plugs to different modules from how it was originally set up.
As Loren and RW964 stated, with the car running:
1. I unplugged the first ignition module and the car continued to die out after 10-15 seconds (original problem).
2. I plugged that ignition module back in.
3. Started the car and disconnected the 2nd ignition module and the car kept running.
Now I know that it's an electrical problem and it's with the one module and/or coil that I disconnected.
I think I'm just going to replace both to be safe.
Thanks again everybody!
