Customer Question

My Kubota 4300 got a lot of use this past weekend. I pushed snow with the front end loader and the rear-mounted blade. On the first day, the engine would occasionally die for no apparent reason. It would restart and I was able to continue the snow clearing.
Yesterday afternoon, the engine started to die every minute or so until now it only seems to run for anywhere from 5 seconds up to about 30 seconds when I restart it.
1. The engine sounds fine when it is running.
2. While troubleshooting, I saw that the hydraulic fluid level was extremely low so I filled it up.
3. During the short time that the engine stays running, I can move the bucket and blade up and down, and the tractor goes forward and backwards without any issues - until the engine dies.
4. The tractor has a hydrostatic transmission.
The tractor is stranded on my neighbor's driveway but I can't keep the engine running long enough to get it out onto the road and over to the barn.
Do you have any idea what might be causing the engine to shut down?
Thank you.

Hi, my name is ***** ***** you for asking your question, I will try and help you out.

iT sounds like your fuel shutdown solenoid is loosing power shutting down engine, check for power when engine dies out, there are 3 wires, one is ground, one is power during cranking only, other one should have power anytime key is on, you can use test light to check for power,

To get machine back to your house remove shutdown solenoid and engine will stay running while you find out if you are loosing power to it.

Possible causes to loosing power to solenoid is low oil pressure switch, low coolant switch, high coolant temp, or a breaker for shutdown solenoid, that is why it will restart right away. You may also have a bad shutdown solenoid if you are not loosing power.
