1993 Chevy p.u., 5.7L 350, runns fine cold, once it warms up it runs badly. It sounds like its cutting out or missing almost like its running out of gas..I changed the the fuel filter, and made sure it was getting fuel and it is. I changed the cap, rotor, spark plugs, and plug wires, also the sensor inside the distributor the one that plugs into the pickup coil but not the pickup coil
