Default what could do this

well friday night was good until my car started doing something, i installed a raptor shift light and did a few 1-3 runs up to about 5700 rpms and everything was good, got out and started messing around later that night, and just past 5000 rpm in all gears it is stuttering, feels like it dies then comes back on and repeat, and if i revved it up to about 57-5800 rpm and held in the clutch the car would die but i could start it back up,
now what does this sound like plugs and wires, opti, or fuel pump or something else im not thinking of
i unhooked the raptor light just because it started doing it after i installed it and it kept doing it so i dont think thats the problem
