Check the Oil. If it is low, the Low Oil cutout will shut the engine off after a few seconds. If the oil is full, try disconnecting the oil sensor. If this makes it run, you will need to diagnose and repair the cutout system.

Proforce powermate 2300 wont run for more than 1 minute, starts in a few pulls....runs than shuts off. Is there a reset switch for the low oil shut off? Only thing i can think of.


It might be a clogged fuel filter or dirt in the float needle. Fuel will fill the carb slowly, allowing you to start it, but it cannot flow fast enough to keep up with the demands of the engine and it runs out of fuel. It sits long enough to refill the carb, you can get it started again, and the process repeats.

The generator has a low oil level sensor. Fill the oil all the way to the FULL mark and try it again.

My powermate 5000 with subaru engine will run anywhere from 30-60 minutes and shut down. One light pull to the pull start and it runs great for another 30-60 minutes. Never a problem to start it back up...


There is debri or dirt in gas tank and eventually it gets sucked up and clogs the screen filter on the end of gas line. Drain gas tank and flush out a few times. let dry and put new gas in it. check your gas can, if it is metal, it may have rust in the bottom of it and it goes in the gas tank and clogs screen, make sure you have a clean gas can that you use to fill the generator.
