If this has happened to anybody I would love to know how you fixed it. Any advice is greatly appreciated. It seems the FC has to be hot or at least ran at speed for a while. Then, when I park, the fuel pump will cut out for a split second, enough to drop the pressure in the rail and cause the motor to stumble but it wont stall completely. It will do this every 15 seconds or so. To make it even more confusing, when I start moving again if I roll into the throttle to much it will cut out also but I can break as hard as I want and it will run fine. However, I can turn right as hard as I want and the car will power right through; but, if I try to turn left, it will stall untill I straighten out. It seems to be both body lean or side "G" induced. But the car also has to be ran hard for a while. If I let it cool for a while it will do fine. One more thing, Even When its Cold, if I try to drift it will cut out. I know theres a lot of veriabls involved. Thanks for all the help.
My fuel set up is :
RP Performance Denso Fuel pump (Good for 500hp)
Aeromotive performance fuel filter
Aeromotive A1000-6 fuel pressure regulator
Aeroquip Stainless swivel AN fittings
Aeroquip SS braided fuel lines
550cc primary injectors, 720cc secondary injectors
Custom CNC Machine fuel rails

 

stupid question........but did you install a new sock when you put in that pump? A dirty sock can cause what you're describing...

 

The previouse owner installed the pump. He did all the work on the car top notch, but it is possible he skimmped on the sock. Thanks for the advice, I wanted some info before I started dropping the tank and pulling the wireing.

Also, I forgot to mention I am using Microtech lt700

 

It's either a dirty sock or rusted out baffles.

 

dont drop the tank there is an access hole in your hatch under the carpet on the drivers side.
