My 1994 pontiac grand prix stalls while driving. It will start right back up most of the time. Some times when restarting is runs really ruff and shuts back down. It happens while engine is cold and hot. I had a bunch of keys on key ring. I removed them and it seemed to fix problem for 2days. But problem still there?

You are going to have to determine which function (spark, fuel pressure or injector pulse) is dropping out at the moment it stalls and that can be difficult to do. You might start by having the codes checked to see if there are any codes to get you pointed in the right direction.
