R33 gtst stutter problem

My 1996 nissan skyline r33 gtst s2 has started playing up about 4 mouths ago it is pretty much stock with the usual mods. The problem is when ever i get to about 4000 revs or higher its like the engine turns off but if i accelerate i can hear the turbo spinning and 3 seconds later it works and then happening untill i turn off the engine or thr engine dies on me any suggestions ive taken it to a turner and he said it might be a weak fuel pump and i upgraded it but it still does it

Well why don't you list what you've done so we can help identify what could be left??

[Sgtminiman]

Replaced fuel pump, fuel filter, airlines, sparkplugs, coilpack

When you upgraded the pump did you hard wire it with a relay to feed it power straight from the battery? If not do this.

What coil packs have you used?

[Sgtminiman]

I cimped the new pump to the old existing wires 

And i got splitfire coilpack

New pump likely not getting enough juice. Especially common if you got a Walbro pump but applies to most.

Search "Fuel Pump Relay Mod" - do the mod, see how you go.
