? about electric fuel pump

I'm wondering if the symptom I have is a sign of a "soon to go" fuel pump... What happens is when I turn the key on, the pump spools up, and I can start the engine and it'll stay running with no problems. BUT when I shut the engine off, and the pump normally runs for a few seconds, it is now intermittent, not steady. It will shut down completely, as it always has, within a few seconds, but as I said, during that point of the engine shutting off and the pump shutting off, it is now a "stop and go" scene... I haven't had a real chance to mess with it, thought maybe it might be the relay, too. I'd rather change that than the pump Thanks for any replies...

Would seem the oil pressure switch would be the likely cause, but not really a problem/issue to be concerned with, IMO.
