Have you checked the fuel pressure? And then, have you checked the fuel pressure after it sits for a couple days? Sounds kinda like your pressure is bleeding off. Could be a couple things like the regulator, fuel pump, etc but you would have to check the fuel pressure first.
Diagnose 1st, never be a parts changer!
