1993 Chevy Blazer stalls then won't start

last week after I got gas, my truck stalled after leaving the gas station. When i tried to start it it would not start. Later that night I went back and it started. I drove it home about 2 miles and it was fine. This morning I was warming up the truck and it was fine. Them it stalled and I started it up, it ran for about 2 minutes them stalled now it won't start. It turns over but will not fire up. I'm thinking if I leave it for awhile it will start again, but I don't trust that it won't stall and leave me stranded.
