Mowing Need help if possible

Have to agree with Kenny. The OP says that it starts right up. If it was fuel starvation it would usually take a little longer before it would fire up.

you've never seen a diesel just shut down when the injectors went dry?

it's about the ONLY way I've seen em go.. just going along at full power.. then the thing coasts to a stop... especially if it will restart and run just a lil bit after setting.. that's sounding like fuel dribbling thru an obstruction.... not an open / closed switch.. etc.

gassers.. carbe'd gassers? now I've seen them sputter as they suck more fuel via choking action and the gove working the throttle butterfly as rpms are dropping with throttle still set high.. grabbing vapos or that last drip of gas from the carb bowl.. etc..

Yes, when you run out of fuel, but fuel starvation cause by a clog filter or obstruction in the tank or fuel line by my experience usually started with a lack of power a few second before dying. But the thing that make me question the fuel is he says that it starts right away after it quit on him. Every time I had fuel starvation on my diesel equipments, it would usually take a few minutes before we could get it started again, and most of the time they just wouldn't start. Once again, this is through my experience, some of you may have experience different situation.

fuel cutoff solenoid would be another possibility.. for instant off, but then run again with little down time.

Any news on your problem?

Here is an update. I decided to start with the least expensive solution and bought a new fuel filter. When I was changing the filter out I noticed there was a lot of debris. After changing the filter I cranked her up and cut for a couple hours with no problem. I hope this is the solution and not the bandaid. I appreciate everyones opinions. I am new to this site and really like it. I will have many more questions to come.

Had the same problem with my now 3-year old Kubota... exact same problem!
As it turned out, a rubber hose coming off the hydraulic pump had weathered and cracked allowing it to break suction... a visible inspection of hoses wouldn't hurt.

DEPENDING ON THE DEBRIS TYPE.. YOU MAY WANT TO CLEAN THE TANK.

WAS IT BIOLOGICAL.. OR DETERORIATING RUBBER? OR RUST?

sorry for caps.. am at work task swapping..

Good news! Have finger crossed. Soundguy also brought up a good advice. :thumbsup:

I suspect that, when you change the fuel filter on that model, you will have to bleed the air out of the fuel system to get it going again.

The 790 has an auto-bleed system.
