Refueled my 2020 Kioti CK3510 and a few minutes later the check engine light came on. It then began flashing DBF in my digital readout followed by error codes F05 then F09. The tractor then begins revving up and down and eventually dies. Any idea what those error codes mean? Kioti error codes are better at hide and seek than bigfoot.

I had the same problem, according to the dealer, he told me the fuel actuator was too cold. Once it warmed up, it ran fine...we had -16 degree weather at the time. Maybe you have a failing fuel actuator. Look really easy to replace, he showed me where is located, near the fuel filter.
