Our old 95 bonnie

This is going to sound funny but our last bonneville was doing the same exact thing as you describe and I did or had done all of the things that'* been posted so far and more.
plugs and wires
new coil paks
new (thing under the coil pak)
new fuel pump
2 PCMs
2 crank sensors
2 cam sensors
Cleaned the cables and cut off the outter plastic
I did some of this and some was done at 2 shops and one dealer and NO ONE could figure out what was wrong with my car.
One day I got mad after picking it up from the dealer and it quit on the side of the road. Now mine like yours would always start right back up and run beautifuly until it did it again. While I was mad and thinking about it. I thought to myself...FUEL PUMP RELAY.
I picked one up on the way home for a $5 or something...put it in and it never died again. That stupid $5 relay cost me over $1000.
It'* cheap and located under the dash on the pass side by the pcm. Against the side of the car...there is a plastic cover and it shows you which one is the FP relay.
Good luck..unlikey but it sure did fix mine. I called the dealer and they said no way. I asked him if he wanted to trade cars for a week and see. He just laughed.

Thats a good thought... Cheap enough to rule out...

We aren't sure what the problem with his car is... But the bad part about the 94-95'* is the Rate of PCM failure... Those 2 years were terrible..

But We'll see what happens.. Its bad when you can't be there to look at it either..

I am glad to hear you got it running... But $239? Thats expensive... It had better have a Lifetime warranty for that price...

For $256 I can get an AC Delco Reman...

Glad you got her running but I feel almost as if you got overcharged..

I've got what seems to be the exact problem. Ever find the solution?
