Will only run for 10- 15 min. then shuts off.

Caution
the manufacture is recommending a cool down period of about 3 minutes to prevent overheating of the combustion chamber. the following is from the manufacture on shut down procedure.

3.2.8Check Stopping of Generating Set
(1)Disconnect the load from the generating set.
(2)Turn off the air switch of the generating set.
(3)Set the speed lever at RUN position, run the generating set without load for about 3 minutes. Do not stop the engine suddenly, otherwise the temperature will increase abnormally, the nozzle will blocked and the generating set will be damaged.
Press down the stop lever. Concerning the electric starter, turn the key to OFF. Turn the fuel **** lever to S position.
Pull out the recoil starter handle until you feel resistance (at this position, both intake/exhaust valve are closed.) and leave the handle in this position. This prevents the engine from rust.
If the engine keep on running even after the speed lever is placed at the STOP position, either turn the fuel **** to the CLOSE position or loosen the nut of high pressure fuel pipe on the pump side to stop the engine.
Do not stop the engine with the decompression lever.
Do not stop the generating set with load. Stop it after the load removed.

Hello, I would check the valve clearance. If the valve clearance is too small, the valves can expand in length as the engine comes up to running temperature and lose compression in the cylinder until the engine cools back down and the process starts all over again

change the oil to the correct specification first. As the engine runs the heat changes the viscosity and overheats or trips the oil alert switch. If its over 10 years old change the oil alet magnetic switch

How big a unit? Model number? Alarm codes? If it runs for 5 mins check the obvious, coolant level, oil pressure and sensor,

Is there a fault?? All UL listed generators including Kohler are required to lockout on a fault on shut down. This really sounds like a problem with your 2-wire auto start connection between your automatic transfer switch and genset. RDT model automatic transfer switch it is the 2 middle wires on the green connector and terminals 3&4 in the generator. close to run and open to shut down. Any open at any time will cause the unit to shut down. The 12 will shut down instantly upon an open because your 5 minute cool down is built into the transfer switch.

Did you check oil level.
The low oil level protection may have stopped it.

hi i have a BGE 3000 petrol generator it was working 1 min and stop the next it runs well but there is no power going to the panel on the front any help? thanks

1) Check tank fuel cap for any vent holes being plugged or rubber components that are distorted.
2) Check fuel shut off valve for being plugged with debris or rust.
3) Remove fuel line at carb to see if fuel is flowing freely.

it sounds like it is overheating. but if only stops for a minute or so dont know if that would be enough time to cool off.When you start it up can you hear the fan running? does it keep running when it shuts down? if it's not running then thats the problem If the fan is running and shuts down when it shuts down then try shaking the door when you start it up the next time or you can try it the first time just to eliminate it being a faulty interlock switch. let me know about what you find about these two ideas.

You may have a 'TEST" mode on your Generator. Ten Minutes is usually the duration of the 'Exercise' function of most units, so I'd like to determine what mode you are starting your generator in. Please comment.
