After running it a couple of hours, it shuts off and won't start. Took it back to the Kubota shop and they changed out a burnt fuse, second one down on the left. This is the second time with the same problem. They told me that I need a new wiring harness, for the price of $2000. Plus labor. Or I can just bring a bag of fuses. They think there is a break in a wire somewhere. Any ideas?

Welcome aboard. A break in a wire won't normally cause a blown fuse unless it is touching a metal part, causing a short to ground. You can connect a small light bulb where the fuse goes, remove the fuse. Then start wiggling wires until the light glows, that's where the short is.

Harbor Freight has this tool, which might help
