RUNNING PROBLEM

1994 Oldsmobile LSS

Engine Performance problem
1994 Oldsmobile LSS 6 cyl Front Wheel Drive Automatic 130000 miles

hi car pros.I have a new question for ya.I went out to start my car this morning and I noticed the engine was sounding a little diffrent. And after about 1 min of run the engine idle way down like under a grand, and the engine started bucking. So I turned it off and tryed to restart it and it did the same thing but now wont run longer than 5 sec, then cuts off. And everytime it cuts out it backfires out the intake, and my warning lights come on except the check engine and a bell sounds. What do you think this could be? I just replaced the fuel pump like a week ago, and its been running great till this morning.
