    I've got a Snapper Walk Behind that has a Kawasaki 460v motor on it and it keeps cutting off. It will run for 10 minutes, 30 minutes, 5 minutes, etc. and then cut off. I have had the carburetor replaced twice and the mechanics at my shop have given up on it. I was talking with another mechanic today and he said it may have something to do with the cooling or coolant. I am not aware of this machine having coolant, but I have to imagine that it has some sort of mechanism that keeps it cool or shuts it off if it gets too hot.

    Anybody have any ideas on how to fix this problem?

    Does it cut off completely or does it sputter out like it ran out of gas?

    Both, at times it will just cut off, then others it will sputter then cut off after about 2-3 seconds of sputtering. After it cuts off I will try to start it and it stays on for a hot second or it won't turn on at all. I'll have to wait half the day to get it to start again.

    I have been able to start and run it for a few minutes yesterday and today and both time it cuts off immediately; no sputtering.

    It could be many different things....try these...
    Clean or replace the sparkplug...check the spark
    If no spark...there is a white wire by the dipstick tube...unplug the wire that goes back towards the handle ..not the one going back into the engine..
    Check your fuel flow..pull the hose off the carb and see how it flows...unscrew the bowlnut on the carb...see if gas comes out..
