2005 Ranger Fuel Pump Cuts out after 1-3 minutes

My 2005 6x6 started cutting out after a few minutes of operation. It dies, and then when you turn the key back on, no fuel pump. I checked the voltage to the fuel pump and found that it was fine (it ran fine when the relay(?) applied voltage) I started gathering more information and began to suspect that the problem is temperature related (it runs longer before cutting out on a cold morning then a hot afternoon). Then I realized the radiator fan isn't coming on. So I jumpered it and found the fan was fine. Next I found the engine block temperature sensor (?) just below the carburator. The jacket protecting the two wires was worn through. I couldn't see any copper, but I ran out of time and will take a closer look tomorrow. I can't figure how these wires, if shorted or open, would cause this behavior, but its all the information I have at this time.

Has anyone seen this pattern before and know a solution? Any help would be much appreciated.

fuel pump cutting out

This weekend I just experienced the same problem and if I disconnect the battery for a minute it will start and Run for about a mile. turning key on and off for me doesn't help mine. IF I find the answer I will post as well.

I was just told to check fuel lines a crak may cause an air leak but not a fuel leak. Also someone said the fuel gets hot and causes vapor lock. He added a shield and it solved the problem.

I was wondering whether a partially blocked fuel line or filter could cause the pump to have to work too hard, and then it overheats and cuts out?

My 04 500 just started doing the same thing. Did you find out what your problem was?

My 04 500 did the same thing this sunday. would only run for 20 mins then shut down. I remembered hearing about overheating so I would put some ice on it and it would start working. I am thinking of a heat shield to keep engine temp off it and the fuel tank but don't want to count on that. I am thinking that a spare pump would be best in case it gives out completely. Does anyone know where the best place to buy would be?
Thanks,
Maclin
