If it takes an hour of running before the symptoms, manifest, it's no wonder the dealer couldn't find the problem. No way they're gonna take that much time with it.
Next time it stalls, get your ear right up next to the fuel tank cap and listen for a woosh or hiss when you open it. If you hear one, the fuel tank vent is blocked.
If that's not it, heat build up could be the problem. Does it have an electronic ignition? The control module or rectifier could be getting hot enough to malfunction, or a connection somewhere is faulty and acting as a diode when hot. Get a can of spray freeze (I think it'd just carbon dioxide) at an electronics shop and shoot it at any suspect component to see if it fixes the problem.
Sounds to me like you've exhausted your options at the dealer, so maybe it's time to go over their head and try to find someone at Kubota at a higher level that can help. I bet there's a thread or two here on TBN where someone has done that and would tell you how they did it.
Good help is hard to find these days...:duh:
BEF, glad you're feeling better, you might be your own worst enemy when it comes time to rest instead of work... I totally understand.
RIP, I believe that because you can pull out the choke, and it keeps running, that there is no malfunction of spark....A carburetor has it's float bowl, where the gas should stay at a correct level when everything is working/flowing. If you turn off a petcock that stops gas flow, your engine will continue to run for a while depending on load. Then when it starts losing it's gas, you can hit the choke to pull the last bit of gas out of the float bowl (which is what you're doing it seems). What kind and brand of engine does it have? Does it have a small vacuum operated fuel pump? these have a small diaphragm that will use the engine block pulses to pump fuel. Usually they last, but you might have gotten some debris into yours or something. You can put some translucent fuel line and a filter on to actually see what's going on.
Ron, I will add conduit contractor to your resume.
I lived in an HOA. Some things good, some not so good. When the cat people get put in charge, the dog's suffer, and vise versa. But all in all, they are designed to protect everyone's home values.
Been staying with my mom since yesterday. She had her gall bladder removed, and since she's elderly, they let her stay overnight for observation. All is well, we are home now, and she's up and about quite a bit. They put CO2 inside of you to inflate you while the surgeon does the laparoscopic surgery. This was part of her pain that they kept her overnight.
Drew, thanks for the tour.
