Fuel Fluke

How old is the tank? If it is old it could have rust and sediment in the tank. Do you think the fuel pickup could be partially blocked and when you are sitting still it is settling in the screen? I had a jeep that did the same thing and drove me nuts. The screen was full of crap from the tank. Just a thought.

At this point I really don't know what to thank! LOL!

I have eliminated the tank being the problem because I stuck a hose in a gas can and ran it straight to the mechanical fuel pump and it still shut off.

I'm pretty sure it's the stock tank that came in the car. I've had it completely out of the car, cleaned, new sock on the sending unit and reinstalled. The tank had no crude built up in it and was in good shape so I reused it.

What I don't understand is I get on the car hard and bark 2nd .. then bark 3rd...and keep it to the floor through 4th... winding the motor up to 5500 RPM each shift with no problems. But when I sit idling for a small amount of time I'm doomed.
