I'd lean towards the relay since you said it runs great after it's started. If there was any sputtering or bogging at all when running or WOT I would say probably a pump. I've looked through 3 help threads so far and you guys are too quick to throw money at your trucks and not taking the proper diagnostic steps. Do a little extra work to fix the problem the first time and save money for mods.
