Its a super charged 3.8 litre put a new fuel pump in and it seems the power is cutting out after it runs, I have 53lbs of fuel pressure and then the power to the pump cuts out after running a few seconds, any suggestions?

This problem kicked the mess out of me the first time I had this problem and it took me a week to figure it out. Today is your lucky day. You need to replace the fuel pump resister, its located behind the pass side headlight. No im not joking.

Nightflyer it is a fuel pump resister and is dealer only. Its not expensive. How the system works is as follows. The supercharged engine needs a lot of fuel volume when running at wide open throttle but doesnt need much when idling or part throttle. So when idling the fuel pump relay directs the power through this resister to drop the voltage at the pump so it wont burn out and lets the fuel presuure regulator keep the pressure even. When you jab the gas the power is directed straight to the pump, bypassing the resister to give the pump full power. Does this make sense? The supercharged engine is the only one with this resister thats why noone knows about it. I dont know how old you are but if you remember the old chryslers with a ballast resister in the ignition system. This resister looks exactly like it.
