KA motor cutting out. Please Help

[RHD240sx]

I have a 90 240sx with a KA twincam motor in it, (non turbo) I just traded my Integra for it, Drove it from st. pete. to home like 1hr30min drive. when I first got the car it only bogged down if I tried stompin on it. Then when I got close to home the car didnt wanta go anywhere at all. I shut it off and started it right up and it ran good enough to make it home. now I go just around the block and it's doing it. The car will sit and idle fine. Any body got any ideas?... New to nissan's... PLEASE HELP....

Nevermind, I figured it out.. Thanks for looking? For those whom are curious as to what had you all stumped..... The small section of the wiring harness that runs from the fuel pump and plug into the msin harness has sum bad connections in the wires which are making the pump shut off when the wires are jarred from vibration or bump....
