In normal operation the fuel pump is triggered by the key being turned on and runs for a few second. After that it requires a signal from the Halls sensor that the engine is actually rotating. if you don't hear the pump when you turn the key on it rules out a vacuum lock in the tank.
Start by replacing the fuses, easy and cheap. There is one on the left side that powers the fuel pump. Remember TOR 2011? See post #416 and #430.

I am also a fan of Halls sensor failure. The fact that it works after cooling down has been electrical problems for me.
Good luck.
