1993 Kohler 6.5CZ23 only runs while holding start button
Here is the story. Out on the water genny running fine for about 5 hours start the main engines to head back to the slip, (about a 30 minute trip). Upon return to the slip I realize the genny is not running any longer. For some reason it shut down in that 30 minutes. Being late and having to working the morning figured I'd look into it later. So here is what I have done and know.
* Generator RUNS while holding either switch (switch on the unit or the remote switch on the breaker panel) but stops running as soon as you quit holding either switch in the start position.
*The oil level is full
* All breakers on
*Both of the fuses next to the hour meter have continuity from one end to the other
*No sign of ant loose, broken, or burnt wires.
*The strainer is clean and clear.
*While holding the start switch and the generator is running it is pumping water out of the discharge
*While holding the start switch and the generator is running it IS NOT producing/outputting enough power to make anything plugged into any of the 110 outlets work.
*No sign of any corrosion on any connection or control board.
*OBSERVATION of the large control board it has 4 LED's that are numbered locations are bottom (LED1) mid right (LED2) upper Left(LED3) Upper Right (LED4) I believe the control board is part# A-229388. I also believe has been replaced by C-229388
-While holding the start button (During engine crank and run) LED's 2 and 3 illuminate.
-Upon release of the start button LED4 blinks 1 time immediately
-LED1 is not illuminating at all during this process.
I am hopeful that someone reading this will know what the issue is.
I also saw in some of the other threads where Viper had posted the service manual (TP-5338), And was hopeful Viper could repost because when I click the link it is responding with destination site not found.
Thanks to everyone that takes the time to read this and reach out.

For sure though if it turns out to be the sensor shutting the unit down you would be well advised to check the oil pressure with a gage if possible to make sure there is actually pressure while the unit is running. Don't just assume the sensor is bad.

Now test the switch to see if it actually is working or if it has failed.
