Fuel Pump Not Priming

My 6.0 swap (2005 DBW) has been running flawlessly for about 7 years. Recently it has on occasion failed to activate the fuel pump when turning the key on which would cause it to fail to start. I cycle the key back to off and on again, then I here the pump prime and it runs fine.

Could this be the relay going bad? The pump?
