Truck wont start/Fuel Pumo Relay Hot ?

Hey guys, my 2000 Dodge Durango 4.7l has been acting up....again lol. So for the past couple weeks my idle has been terrible and the truck dies at random quite often. When starting in the morning I have to rev for a bit or else she will die on me. When the truck dies while driving the fuel pump relay is burning hot. Like too hot to touch. Swapping relays with say the fog light relay may or may not get her started again(depends on how the truck feels). Also when I swap the hot relay with the fog relay, the fog lights will come one meaning the relay still works. So after some research I decided to drop the tank(not my first time doing so) to check electrical connections to the pump and they seem fine. The pump was a replacement pump I replaced about a year prior. Decided since it was under warranty I would swap it out. Went to Autozone. And got another Delphi pump. Here's where it gets weird. When I hooked the new pump up and went to turn the key, there was no pump hummimg and she didn't start. So that told me the pump was getting no power. I thought the pump was defective so I swapped it out for yet another one. After hooking the 2nd replacement one up, I now hear the humming although it sounds a bit off but the truck still wont start. Its worth mentioning that the fuel pump relay was one of the first replacements I tried. The relay isn't the issue unfortunately. It clicks every time I turn the key as it should. I inspected the relay box but couldn't find any issues. I know at this point that the relay is receiving too many amps because it's hot. However I have no idea how to fix this issue. @ 250k miles everything seems to be going out. But I still need this truck as it is my only source of transportation. Any help on where I should turn to next to get this truck back up and running is greatly appreciated everyone! Thanks!

Something is up in the wiring would be my guess...can you trace your power back to the source for the pump?...any bad grounds causing too much resistance?...any frayed wiring, ect.....
