I have a 743B Bobcat with the Kubota V1702 4 cylinder engine. It will run fine then it will just quit running, it will start right back up but it runs rough, it will do it ant any time, it's doesn't matter if it's only been running for 10 minutes, or 5 hours. Once it dies out, and I restart it, it runs rough the rest of the day. I have gone thru the entire fuel system except from the injector pump to the injectors. I'm at a loss as to why it does this, any ideas??

Mine (I also have a 743) is doing the same thing; it started acting up last week. We had a real cold spell, though, and I suspect gelling/ice in the fuel. It is good now, after running 911 through it, putting some Winter Powerservice in it, and lots of cranking. What have your temps been like?
Welcome to OTT, by the way. This is a great site, and all manners of Kubota are welcome!

It's done it when it's full of fuel, I keep it topped off with fuel as much as possible, I also replaced the lift pump made no difference. It does this at any temputure, the last few weeks the temps were in the 70's, and 80's. It will do it at any time, and temputure.

When you said lift pump it made me think of what my buddy went thru with his bobcat. He plumbed around his lift pump and installed a electric diesel fuel pump and solved his problem.
I know that fixed my buddy right up. That was several years ago and he hasn't had any trouble with his since.
