Fuel 2006 mustang gt

[Uplegger1]

I have a 2006 mustang gt 4.6 3v 5 speed manual and something keeps turning off my fuel pump and the car stops getting fuel and pump won’t turn on so my car won’t start! I let it sit for a day and then it will start right up and drive! I have a brand new fuel pump and relay! My car keeps doing it! Anyone have an idea?
Thank you!!

Check the wiring under the fuse box under the hood.
