I'm having the same issue, but not causing a mechanical issue (that I can tell). It only does it when the truck is moving.

Check the fuel pressure and see if it remains steady.

Check your power and ground on the control side of the relay. The positive side should be hot at all times and the ground is activated by the ECU to turn the pump on. It should be grounded any time the key is on.
