Kohler Generator fault code OF reset

[Pilot]

My Kohler 5E Gen shut down yesterday after running 2 hours. The code is "OF" or Over Frequency. Now, when I try starting it just sputters for 20 seconds and shuts down with the same OF fault code. I'm thinking maybe it just needs to be reset, but not sure how?

It was a fuel cooling pump

105 total hours on this generator
Total costs for repairs over it's long life: $2000 (thus far)
My opinion of Kohler: P*O*S* product & quality.

Ouch... I went with Kohler for thier reputation, maybe I screwed up.
