Have you checked fuel pressure or for injector pulse when this happens?
Lets do some basic diagnosis first before throwing parts at it.

I agree If you didn't already have them you could have bought a fuel pressure gauge set up along with a set of noid lights and a multimeter with what you've spent already. One of these tools should lead you to results.

ok i did figure out somewhat what it is my ignition control module was shutting my injectors down but still have a small problem, it dont shut down anymore but when you tromp on the gas and let off quick it almost wants to die, my fuel pressure is good new fuel pump, new fuel pump relay, running soso better than not running at all
