Had the same problem with my Onan, Check the bridge rectifier, Simple and cheap fix.

I may be late to the table but I had a frustrating issue as well. http://www.yachtforums.com/threads/kohler-7-5-r-generator-shutting-down.24973/
rcrapps helped out with a schematic. Everyone with a Kohler 7.5R should carry spare, rough service fuses. There is a 10 amp and 2 amp in the board at the rear of the unit. My 2 amp fuse was burned out although it didn't look it. I confirmed it with an ohm meter. Runs perfectly now.

Since the last thread concerned a generator issue. I have my own issue with a Kohler, model 8E.
Generator starts up easily, then shuts down after 4 seconds. This happens every time. First I thought it was a fuel issue since the generator sat idle for a few months. Carb was taken apart, cleaned and re-adjusted. Impeller was checked for blockage. Elect fuel pump was checked for pressure.
Generator still only starts and then shuts down after 4 seconds.
I bypassed the Oil pressure switch, High temp switch at different times.
No help from Kohler. I was referred to the closest authorized repair facility. They want to come down to diagnose the problem at a $95. per hour charge plus $2.40 a mile. The shop is 140 miles away. SO I am trying to diagnose the problem myself. Any ideas?

Did you ever get the problem solved. Mine does the same thing. Even a Kohler authorized shop can't fix it.
