You need to do a fuel pressure check.. You will need a special fuel gauge and the appropriate fittings and adapters are needed to properly test the fuel pressure.

1. Relieve the fuel pressure.
Remove the fuel pump relay form the Power Distribution Center (PDC) Start the engine and run until it stalls. attempt restating the engine until it will no longer run. Turn the ignition key off. Disconnect the cable from the negative battery terminal. Replace the fuel pump relay in the PDC. Any if you get any trouble codes at this time you will need to see a shop to have them cleared.

2. Disconnect the quick-connect fuel line fitting fuel gauge into the fuel line using the appropriate T-fitting and adapters.

3. Start the engine and check the pressure on the gauge, your reading should be 49 PSI with the pressure with the engine idling.

4. if the fuel pressure is not 49 PSI:
1) if fuel pressure is higher you could have a pinched of clogged fuel return hose of pipe. if the line is not obstructed check the fuel pressure regulator.
2) if fuel pressure is lower check the fuel filter, look for a pinched of clogged fuel hose between the tank and the fuel rail. check the pressure regulator for malfunctions. Look for leaks in the fuel line.

Hope this helps.

I doubt the regulator is bad, the fuel pressure regulator is after the injectors in the return stream to the tank, more likely it is the fuel pump.

I would check the fuel pump relay and the fuse for the sending unit and also would take the line off just in front of the fuel filter to see if I am getting fuel to that point but check the fuel pump relay and the fuse first

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?
