    i have posted about 3 threads already just to try to fix my problem but still i am having the same issue. today im mowing and its about 92 degrees and the grass im cutting is particularly high however i am cutting it in 2 passes so it shouldn't be a problem with bogging down the motor. after i started it up i worked for about 15 minutes before the engine suddenly lost power and shut down. than i would start it right back up and it would take about 2 passes and cut out. i also noticed that with the blades off when i wasnt driving around my rpms fluctuated rapidly upppppppp and downnnnnnnnnnnn and so on.

    fluctuations like that are usually a dirty air filter or water in the carb.

    My initial thought would be fuel starvation. This could be a partially blocked fuel filter or dirt/dust in the carb' bowl. With the heat you're experiencing there could be a fair amount of evaporation. All the more need to make sure the fuel supply is 100%. Check condition of fuel lines, no tears/leaks. Does it have a fuel tap? Make sure the fuel is flowing from the tap by disconnecting the fuel line from it. Blocked up fuel tank cap? Is there a cut out solenoid on the carb? Could be defective.

    Have a quick check of these items. First line of attack :dancing:

    My first thought is a blocked vent hole on the fuel cap, unscrew the cap all the way and then just barely screw it back on. Now give it a try, this would be a easy fix, I have this problem from time to time. Could be just a dirty air filter or fuel filter but my bet is on the fuel cap.

    I was thinking about the fuel cap issue as well. What engine does your machine have?

    my old JD's used to eat a fuel cap a year, try loosening it first, it may also be your air cleaner, Kawi's DON'T like dirt at all!!

    Did you put the large kohler fuel filter on it. Lowe's / Home Depot is still open. Is the fuel filter still empty when it shuts down?
