Ford escape 2005 furl pump not turning on.

What is your question?

Ok ill try to timeline this out for clarity. Day 0 car runs fine Day 1 i come out and car cranks strong, turns over then dies.... continues to crank strong but wont turn over. Day 2 - i find the inertia shut off switch is tripped. I press it and it clicks. But still no start Day 3 i realize the fuel pump isnt running, i change it. No start.... i then change the fuel filter and the car fires up just like normal days. BUT 10 miles down the road, the car dies again. Day 4 inertia switch not tripped, all fuses checked and good. There is 12v going to fuel pump but still no start. Day 5 i jump wires from the battery to the fuel pump and the fuel pump starts running. Please help!!!!!!!
