It’s still getting fuel and lots of air.

A diesel will even run on it’s own crankcase-oil if it has a bad gasket or seal and gets air.

Isn’t a generator engine set up to run at full speed and only one speed to produce the correct frequency of power.

So when you say “wide open throttle” is it at 1800 ( 4 pole speed) or 3600 RPM (2 pole speed) or something higher? Does the RPM stop climbing or is it going into a runaway condition? How are you stopping the engine?
