Can you smell gas, like it was flooded? If so, you want to check the coil to make sure your getting enough spark.

I had extremely similar issues with my 87 suburban, cheapest easiest to check is the fuel filter, about 8 bucks and 20 minutes of work, then pump.... then keep running the fuel and ignition systems. Doesn't sound readily like a spakr issue, but its possible. Good luck.
