Well, the car continues to die; usually when I hit a bump, turn the steering wheel or put it in gear (this one usually only happens when putting in drive). We already replaced the starter, we've tried 3 different batteries, all of which still get the problem. Anyone have some answers? Or maybe you'll need more detail. Oh yea; 1991 Z28 5.7L

 

Short or bad ground to either the ECM or the distributor would be my guess.

 

What are the idle RPM's at in Park/neutral?

 

I think they are right around 750, I'd atleast be able to tell you between 500-1000.

You may want to check the wires inside your steering column. If you have a loose wire in there, or in your console,you could possibly have that problem. As has been said before "Check all your grounds!!!!!!"
