Lift Pump "signal"?

What tells the lift pump to start and stop. Mine is quitting after 4-7 min idle time and ther is no power to the pump when this happens. I turn the truck of and then start it right back up and the power is back on at the lift pump.

So, What is telling it to start and stop?

There is a relay in the power distribution box under the hood for the fuel pump and it gets its control from the PCM if my memory serve me right...
