Anyone having troubles with their Kubota rtv 500 efi staying running when you first start machine and the outside air temperature is below 40 deg. F ??? It will start & stop as soon as tranny hydraulic pump kicks in.If you get it running long enough you can hold your foot on throttle so you can keep it running till it runs for 5 minutes and warms up enough to idle on its own.Any Kubota mechanics out there ???
