I had the same problem with a simular generator. I took it to a repair shop who told me it was the "low oil sensor". They fixed it and it lasted another 1.5 hours. I told my-self I would monitor the oil and cut the "low oil sensor" electronic line. It has laster 12 years as a backup generator running at least 200 hours per year. I still have it but have switched to a larger generator. If you, or whoever uses it, can watch the oil level, then cut this line, it will be fine. This sensor is for those who are not able to measure oil level !!!

Your gas pressure is too low and you may not have a large enough supply pipe. You need at least 10 inches of water column with the engine running to operate an LP vapor fueled engine. Because the engine is starving for fuel, its governor opens the throttle to WOT (so it goes to high revs) but there isn't any fuel to make horsepower with so the output voltage falls and the undervoltage alarm trips.

This sounds like overheating. These small generators don't have overheating protection, but if a low oil pressure or low oil level is present it may be the reason for stopping.
Check the oil level in the starting conditions and again when it stops. It may become under the "stop" level and after some time the precipitated oil has reached the "start" level. The same may be with oil viscosity and oil pressure.
Try to add some oil or change the oil with bigger viscosity.
