    Can anyone tell me why the Kubota diesel engine in my mower starts and runs fine for about ten minutes, then sputters for about a minute, then quits completely. I've repaced the lift pump and fuel lines.

    Any ideas ?

    Have you checked the fuel shutoff solonoid?
    After it shuts off how long before it starts again?
    Which fuel lines did you replace? From the tank to the lift pump or from the injection pump to the injectors?
    How much fuel pressure is it seeing? Check to see if the fuel pressure is dropping as it stalls.
    Is there possible a failing safety switch somewhere? A low oil switch takes the oil heating up/thinning out before it shuts the motor off?
    Fuel filter?
    Maybe bad suction tube in the fuel tank?
