Generator Quit Running And No Fault Codes Or Power

Our generator just quit working all of a sudden last night. When I woke up and went outside to check the fault codes there is nothing,  nada. There is no power to anything concerning the Genset.

UPDATE
I just this minute pulled the 5 and 10 amp fuses on the panel to double-check them and both are fine. When I reinserted the 10 amp fuse the Genset immediately cranked and started.

What could have caused this to happen?

Most obvious...... Check fuel level, under a 1/4 tank or so genny will shut down to prevent you being stranded.
Genny only needs fuel and air to run,  If fuel lines intact and airway unrestricted, look to overheat shut down, If remote fan on your model, Is it running ? Breaker on genny both reset ?  Coolant Level OK ?
Good luck, someone with same model as yours will probably chime in.

It's still running almost 5 hours later.

Fuel tank is almost full and coolant is at the proper level.

You may have fixed a bad connection at the fuses. Chances are those connections haven't been wiped since the coach was built. A 12 volt connection doesn't need much corresion to make it fail.
I hope you solved your problem.

Another common easily fixed & usually inexpensive item is the oil pressure switch on the generator. 

In this case, it does seem it was only the fuse needing reseated and cleaned.

Good thoughts on the Buss fuses with such little contact area.  When I get a chance I'll buff things up.

Small vibration?  Happened to us about 150 gen hours ago.  Buffed the connections and all has worked well since.
