R33 Rb25det starts runs then dies and struggles to start

[Digger_x]

Hey guys im new to the skyline family. My problem is that my r33 skyline starts and runs for abit then dies without struggle all the accesories like turbo timer, techos, all the dash lights .etc. stays on but then has trouble starting again. It crackes over and starts for a seconds then dies again. After multipul cracks or turning the key all the way off for a seconds then back on and crank she starts

The previous owner had an immobiliser problem so i changed it out but had no idea where or how to install a few wires like the immobilser bypass and a couple wires that go to the ignition. Do yous think that'll play a part in my problem.

Could be lots of things but sounds like fuel (pump?).
