My recommendation is to isolate the problem....since you have the new pump back, get a clean bucket of gas jug and run the pump, no filters, to see if you can continuously run the pump for an extended period of time. Then add the filters in the same test - one at a time.
Then hook it back up the car and run it with an external power source to verify it is not the vent ofr return to the tank. If you can get it to run like that then hook the existing wiring up to see if it will continue...etc...
Take it step by step until you hiccup again....
Good luck!
