Code 25 on 8KW Onan

Yahoo Message Number: 84112
With so many members of the group with the diesel Onan generator, I was wondering if any had experience with the 25 code. The generator will run for a good 45 minutes, the rpm's will fluctuate and will stall and generate a secondary service code of "25." That is a governor issue. The real question is, has anyone found the fix a fuel delivery problem versus electrical?? I have installed new fuel lines last year, and did a complete service in October. I am wondering if I have an intermittent fuel pump, the genset has just under 1300 hours. Thanks for any help.
