!991 S10 2.5L Issues

I have a 1991 S10 2.5L I have replaced Ignition Control Module, Ignition Coil, Rotor, Distributor Cap, Plug Wires, Plugs, Map Sensor, O2 Sensor, Fuel Filter, Fuel Pressure Regulator, and Fuel Pump. It is starting to run better but it is hard to start and once it does start it seems to idle ok but when I go to accelerate it cuts out and dies. Any Suggestions?
