Try loosening the gasoline cap on the engine. My snowblower acted the same way until a mechanic told me it sounds like the engine is not getting enough air. Some gasoline cap vents go bad and starve the engine. If your engine continues to run you can buy a new gas cap.

Hey John!
Have you check the OIL some of these engine have a low oil shut-off sensor feature built-in ?

Exmark lazer HP 19 Kawasaki 50" deck new PTO and new relays blades engage for 30 minutes then shut off engine on. After cooling will engage for 10 minutes then shut off


Engine valves need adjusting.
symptoms: starts ok, runs until engine reaches max temp loses power then stops. can't restart when hot. once restarted runs for a while stops again.

There is very little clerance in these valves and temperature alters the lenth by a few thou and the valve don't close fully losing compression, once cold the valves shrink back enough to create enough compression to start again.

My Kawasaki twin engine model FD 590 on my lawn tractor sputters, looses power and shuts down after about 15 min of running. Will star after it cool down. Cause please??


Immediately check for spark after it dies. A failing ignition module will quit after it gets hot (about 10 minutes) then work again after it cools. Other causes could be a blocked tank vent; try to run till it starts to act up and loosen the fuel cap. See if it starts to run right again or if it does die it starts right back up. A sticking shut-off solenoid, sticking float needle or partially clogged fuel filter can also cause these symptoms. They let some fuel in but not enough and eventually the motor starves for fuel. then slowly the fuel fills back into the bowl and it will run again for awhile till it runs out of gas again.

LT133 lawn tractor starts then stops. no spark,has gas filter ok,cleaned safety cutoff switch under seat. mower starts up,runs for 20 sec then stops.


Does the engine start up every time right when it shuts off, or will the engine not start until it's cooled off? And when the engine is running for the 20 seconds........ does it give any indication that it is going to stall, or does it abruptly shuts off with no indication of stalling? Let me know and I'll try to get back to you as soon as I can.

Your ignition switch is bad. The contacts inside are not making good connection to send signal to starter solenoid to start engine. Now the run position contacts are bad causing the engine to shut off. If the engine cuts out on you again, wiggle the key in the ignition at the same time start the engine using your screw driver. If the engine starts back up again, wiggle the ignition to see if the engine hesitates and stalls out again. If so, replace ignition switch assembly.

I have a riding lawn mower. It starts up ok, then light blue smoke starts coming from the engine. The smoke is so thick I can barely see my hand in front of my face. The engine is only two years old and I...


Is the crankcase full of fuel? Remove the dipstick from the engine ( do not wipe clean) and walk away from the engine and in a safe manner hold a lighter to the dipstick. If the dipstick lights and burns then there is fuel in the oil.
If there is fule in the oil then drain then change your oil and rebuild the carb being sure to replace the inlet needle. It is also a good idea to install an inline shut-off valve in the fuel line. Then start and run it again. It will take about 5-10 minutes to burn out the residual oil/fuel from the exhaust. After that it should clear up and not smoke anymore. Dont forget to shut the fuel off when the unit is not in use.

When your ignition coil get to engine temp. it will begin to lose its power, therefore your engine will eventually shut down, when it cools it will start up again,
