2012 doosan towable air compressor c185 will run for hours while not under a load when under a load the machine will run for about 30 minutes. I have changed all fuel filter and check coolant & air filters.

Sounds like it may be shutting down on hi temperature. Check the oil level in the compressor part of it. It may be low on oil, or have a bad thermostat. Check oil temps in and out of oil cooler. You should see a 30 degree drop, give or take a few degrees. If the oil level is OK, and the thermostat valve is opening and allowing oil into the cooler, then it may be your temp sensor.

How? Slow to a stop, just quit as if turned off?

No control panel indications?

Assuming it's reasonably level, are the radiators working and not blocked? Fans?
