I had a problem just like that on my blazer and it turned out to be the wire harness on the fuel injectors. It could also be your fuel injectors, had to replce mine at 85000

try replacing the throttle position sensor
SOURCE: was driving truck and stopped at a light.truck
i would check the dist.cap and wires.this seems to be a place to start.check all vacum lines.would also check fuel pump pressure.you need to determine if its fuel or elect.may also consider cam sensor.
