P0033 fault code- fuel pressure regulator ?

Hey guys today my 2001 GMC diesel dually was chugging along with 4000 lbs of gravel in the bed . I was halfway home when out of the blue I had no power and the service engine soon light came on .

Somehow I limped it home . Hooked up the code reader and P0033 came up . I think that points to the fuel pressure regulator . Truck has 190k and I change fuel filters every 15k . Any thoughts on that fault code ?

I don't see or smell any diesel fuel . The truck will start but virtually no throttle pedal response . It goes to about 2k and then lays down . Any help is appreciated.
