stalls

i own a 1995 bonneville 87000 miles, i have been having problems with it stalling going 65-70 mph or just going 5-10 mph, sometimes it restarts real easy and other times it wont restart at all, i have replaced- FUEL PUMP, RELAYS, ECM MODULE,CRANKSHAFT SENSOR, I even put it in a GM garage and they replace all the same parts that i did, but with GM parts instead of auto zone parts like i did, but with the same results still wont run

i had that problem a little over a year ago and changed all the same parts and had the dealership looking at it with no results. Someone told me that a bad cam sensor acts like a bad cranck shaft sensor so I replaced it as well. I never had a problem after that. Worked for me, maybe it'll work for you.

Does it tend to stall when you are just driving, or does it stall when you try to open the window, turn on headlights, or something like that? I had a similar problem and I noticed that it would stall when I opened the window. After it stalled the window would no longer work. I was told MAF sensor, crank sensor, fuel pump, etc... but what it ended up being was a bad ground. Check out this link:
