1989 Chevy Truck Truck dies at idle, but will restart right

I have a 1989 chevy 1/2 ton truck that will idle, but then dies out. Have replaced all the sensors with new. It has a new fuel pump. It will restart right after it dies, but at the next stop light, will idle for a bit and then die again. There is no catalyitic converter, and also no check engine light. Can it be a faulty ignition coil...
