We went camping a few weeks back in Hungery Valley. While running the gen it would run long enough to charge our batteries for a few minutes and shut down. Once batteries drained, I'd have to jump sta...

I agree with nayther, but the process for obtaining the second level code might be different depending on your model generator.
But, error code 33 isn't used to avoid confusion with error code 3.
This document seems to say that there should be a secondary code:
https://manuals.heartlandowners.org/manuals/Electrical/Generator/Onan%205500/Onan%20Troubleshooting%20Codes.pdfThree blinks indicates a service fault. Press Stop once to cause the two-digit, second-level fault code to blink. (Pressing Stop again will stop the blinking.)The two-digit code consists of 1, 2, 3, 4 or 5 blinks, a brief pause, and then 1 to 9 blinks. The first set of blinks represents the tens digit and the second set of blinks the units digit of the fault code number.
For example, Fault Code No. 36 appears as:
blink-blink-blink—pause—blink-blink-blink-blink-blink-blink—
long pause—repeat
Out of curiosity, have you checked the oil level? I had 145 hours on my generator and was fixing to do an oil change when mine started shutting down. The code did show "oil fault" or something like that. Turns out it had ran low on oil.
I have checked the oil level. It is fine. Now the lights not flashing. I'm going to have start it up and let it run a few hrs and see what happens
