I have a Kubota FZ2100 AWD zero turn mower. I just purchased this from a Dealer and it was running fine. (I bought it with a bad freeze plug in the head and repaired that) Now after I have used it several times mowing 4 acres it is missing on one cylinder. This has the Kubota 905 series 3 cyl engine. I have cracked the lines at injectors and one is not getting fuel at all. I removed the line to the injection pump and it is clear. Also removed injector valve at pump and it is clean. Reassembled and still no fuel at injector from pump. Do I have a bad pump? I have heard that is kind of rare. Unit only has 782 hours.

Did you remove the head to fix it? If so you may have tightened one of the fittings on the pump too tight reinstalling the lines and turned the barrel. That will cause it to not get fuel at lower rpms. Your pump has either one or two screws holding them in, look at the slots and see if the one that's not shooting fuel is turned compared to the other two.
