Starts easily, run for 5 to 20 minutes and then

I had a car in my shop that would run for two min. and die. wait a min and would start right back up. Turn out to be a cracked rotor , the crack would open when it warmed up enough. thy that.

Some engines have a low oil cutoff switch. If the oil level drops to a certain point it kills the engine. Your oil level may be close enough that after starting and running for a little bit the level drops enough to kill the motor. After sitting for awhile the level rises enough to allow the engine to run again check the level and add oil if necessary.
Hope this helps.

If this unit dies under load conditions, decrease your load and try it again.
If this happens under no-load conditions, check your fuel supply. Start with the filters, then check pressure and flow.

There are many possible reasons from stator output voltage to sensing, to fuel to control boards. A good place to start (as the unit does run) would be with the fuel system, if it has sat a long time it won't help. Also the fuel filter. try conencting to an external fuel tank versus the vehicles, as sometimes pick up tubes in main tanks can be an issue. Also check the correct oil level and viscosity / and oil pressure switch. Failing that I recommend a service center, as there really are so many causes, I cannot list all on here.

Do you have an air filter on that thing? Sounds like it's straving for air.

More likely the switch is bad, and only make run contact when in the start position.
Easy to test the switch continuity with a ohm meter when it is not running.

Alternately,



• Turn-off all lights first.

Run your pump or water start motor.



• When the motor is running,

Turn on the lights , one at a time.

Test the solinoid with an ohms meter and if the circuit is open replace the solinoid.

Check the fuel filter. My company designed hybrid generators that are far more efficient. They use batteries to power your equipment, and the generator runs intermittantly to recharge the batteries when needed.

does it have original oil in it? if so they use a lighter weight oil than recommended for engine break in. change your oil and filter and see if that doesnt solve it.could be thinning out loosing pressure when hot. i have seen this beofore.. :)
