I am having the exact same problem with my 96 GMC 5.7. Parts replaced and thrown at it with no sign of improvement: plugs, wires, distributor cap, rotor, can shaft position sensor, crank shaft position sensor, coil packs, coolent temp sensor. fuel pump, EGR, Ignition control modual. It does not have cats as it is an after market exhaust and cats have been removed. What is left?
