94' Acclaim stalling

I have a 1994 Acclaim with 3.0L V6and about 135,000 miles on it and have had it for a few weeks now and has ran fine up until a few days ago. The alternator went out about 3 days ago and i replaced it and ran fine until today when the serpentine belt on it snapped. I went to the auto parts store and bought a new one and put it on and about 5 minutes after i got the belt on there and started it up and started driving it stalled on me. This is the first time its stalled on me and stalled a few more times while driving it about 3 miles home. It seems to only stall when im stopped or coming to a stop. I was wondering if it has anything to do with replacing the serpentine belt since it started doing this after replacing it or is it just a coincidence and happen to be like a fuel filter (http://www.carforums.net/showthread.php?t=59243#) or something like that. I dont know very much about cars so if anybody can help me out it would be appreciated.
