Default B3300 quit running

Working on the trails today, clearing brush and dragging it clean, when my Kubota quit running. I was pulling a backblade in low gear 4wd at about 2K RPM when the tractor dropped to about 800 RPM and started sputtering. All gauges show normal, she turns over but I can't get more than that same brief little sputter. No fluid leaks. Any ideas?

That sounds like no fuel.
Have you looked in your tank to actually verify that you have fuel?

It can be more than what's in the tank. Check for flow at the bowl and through the fuel system before the pump. There are a lot of things that can plug up the system. Also check the fuel cap to make certain it has venting flow.

Yep, gauge reads almost half, and I see fuel. It sure does seem like a fuel issue.

Dumped a can of fuel in and 5 gallons brought me up pretty full on a 10 gallon tank. No improvement. Too late and I'm too tired for tonight, but tomorrow I'll start checking out fuel flow. Of course it had to happen about a mile from the house, and a long hot walk did me no good. Still under warranty and the dealer is 10 minutes away so I'll give him a call if I can't figure it out.

Could have water in the fuel. I would take a new filter with me when I went back.

I talked to a neighbor who uses the orange and he said his son has a B series. His son changes fuel filters like he checks the oil, constantly. They think the plastic fuel tank condensates more easily. I happened to have a spare fuel filter so I changed that. Surprise, the old filter had a lot of waxy black junk all over it. However, after changing the filter, my 3300 still wouldn't run more than 5-6 seconds before stalling out, apparently still fuel starved. Finally, I siphoned the fuel out and poured in 2 gallon of fresh diesel from another source. After a couple tries and priming the filter a bit, I got her running. The bad fuel was off road diesel. The new fuel was on the road diesel. As soon as the red fuel cleared the bowl, the engine ran smoothly. Hooray. Now my orange girl is back in the garage where she belongs. Tomorrow, I'll pour some of the bad fuel into a clear container and see what I can see. Planning on taking back where I purchased it and see what they have to say. I wonder if the offroad diesel is lesser quality than the regular diesel? Heavy duty equipment probably uses heavier duty filters and maybe more of them, so maybe they aren't as affected .
Thanks to Shaun, Beck, and Bulldog for taking the time to help. I think I'll use over the road diesel (from a different vendor) from now on as I don't need the long walks back to the garage.

Glad you got it going again.
No matter the fuel that you use well you might want to consider an additive.
I use to work with a company that is associated with the petroleum industry and I can tell you from experience that your best bet on getting clean fuel is from the highest (larger) volume dealers you can get it from. I suggest you dont buy from the smaller mom and pop outfits if you can. Too many horror stories with fuel dispensers, cars, and trucks. Not everyone has that option I understand and Im all for supporting the little business owner but fuel is a different story for me. Right now Im buying my diesel in 5 gal cans from a Loves Truckstop Travel Center until I can get a better way to fuel.
Best of luck

Mud, that's advice I'll take to heart from now on. I'm closer to the freeway station than any other but a friend owns the BP where I get the over the road diesel. And I always try to support the local guy, though not much of his income comes from fuel sales. But I sure don't need to take chances with fuel. I'm also filling from 5 gallon cans and using stabil as an additive. Maybe I need a new additive , also.

The black slime that was in your filter is a bacteria. I have had the same problem all summer finally got it straightened out. Get some antibacterial treatment for your fuel it will hopefully cure your problem. The new fuel mixes combined with the plastic tank doesn't help the problem.
