Hi. I had the same problem on my 2004 Dodge Ram 3500 Cummins. I went to the dealer and they did a bunch of diagnostics and they replaced my fuel pump. At the same time they put in a retrofit kit that moved the fuel pump to the inside of the gas tank. I have not had the problem since. The cost was about $1,200, but my 100,000 mile drivetrain warranty covered it and I had to pay the $100 deductible.

do you still have the old style lift pump. located on the fuel filter housing or has it already been updated to in tank style. sounds like that to me. i've done a ton of them. chrysler has a whole conversion kit for this mod

Please clarify the "loosing power" does it lose power and shut down or does it loose power but will idle? Your Cummins is electronically controlled so oil condition is important, fuel leaks, oil leaks, leaks in the air ducting between the turbo and the intake, sensors, water in the fuel. Do you get an engine light when this trouble happens? Dodge uses a lift pump to carry fuel to the the injection pump, is it working?

It sounds like it could be the transfer pump. Turn the key on and then crank the engine for about 1 second but leave the key in the run position and listen for the transfer pump to run. It should run for about 15 seconds after you stop cranking. If not, then you will need to replace the transfer pump with a in-the-tank conversion kit if your is mounted on the side of the engine block below the fuel filter housing. If you already have the in-the-tank pump then it might be siezed or the "sock" might be plugged up with alge or other contaminants. I usually lift the bed rather than removing the tank to replace the fuel module. If the check engine light is on you might want to have it scanned for codes to make sure since the modules can be spendy.

it doesn't have a fuel pump relay it has a fuel pump control unit and it is located on the chassis back quarter drivers side near the tube cross member for chassis on top of chassis rail near bed mount. locate the rear springs front perch and it will be above that on top of rail.
hope this helps. good luck and please ask any question you have.
