Try opening the genset door and see if it shuts off after 30 mins. If it still shuts off immediately disconnect the fuel pump line to the carb and see if it is still pumping fuel. If your fuel pump is working when hot restart the engine and when it shuts off immediately check for spark a failing coil will sometimes not produce spark when it gets hot. It could also be one of the sensors but if you try these 3 things and report back you will solve the issue.
This is the problem with my adding to an existing thread lol. I'm not sure who the questions are for. My genny is an Onan 4000, 4KY spec K. No low oil level sensor but the oil level is good. Code occasionally show "36" which is "engine shut down without command". I do have fuel and spark after shut down but still won't restart until it cools down.
