Our Onan Diesel generator starts up just fine but then stops after a couple of minutes. It will start back up easily but then dies again. It does not matter if it it loaded or not.
I'm not sure what to do. Any help would be appreciated.
Thank you,

Are you not getting a code on your panel when it stops?
Too much oil. Drain a little out. Restart.
Sounds like the fuel pump
I had a similar experience a few years ago, not sure if this will apply to you or not. I was performing the annual maintenance on my AquaHot and for one reason or another, decided to start the generator (12500 QD in this case). It would run for a short period (1 - 2 minutes, perhaps) then stop. I restarted it and it repeated the same behavior. I may have done it once more before the real head scratching started. It then occurred to me that it was drawing air from the open end of the filter housing on the AquaHot (as I had the fuel filter off the unit as part of the annual maintenance). I replaced the filter and the "issue" was resolved.
change the air filter; change the gas filter.
