It dies

[dhofer]

I have a Kubota 4330 tractor, I can be using it and it will flat out die, restart it and dies again, it don't matter if I its sitting or driving it or if I leave the clutch in or out it usually dies right away. Any ideas what might be wrong? All filters have been changed and fluids are full.

Would you say it is a sputter and then dies? Or .....dies quickly?

I would say you have a fuel problem, bad fuel, filter and or pump problem - and based on what you are saying - sounds like a pump delivery problem.

you have changed all fuel filter and checked for anything "wrong" with the lines?

If it dies like you shut off the key then your problem is with the fuel solenoid or system.
If it's sputtering and slowly dying then it's probably a delivery of fuel, or fuel quality issue.

And just for future info sakes, give your complete tractor info, like a L4330DT or B4330HST or whatever you have, it will get you better answers to questions as each tractor series, model and type can have a unique issues.

It dies quickly, and I changed the fuel solenoid, its been acting up for about 6 months, all filters have been changed, sometimes it will start right back up and sometimes it sits for a hr then it will start. Its a L4330 HST

After having said that , I would lean towards the fuel pump......
What is the price tag on one of them thar pumps from kubota ?

My Bobcat mini x had a problem about like this. Turned out it had a cracked battery terminal. Replaced it and the problem went away.

Could be as simple as a bad HST safety switch or even the seat switch, both can cause it to just shut down while using it if they are bad or misadjusted.

Don't know if kubotas suffer from the same malady as other tractors, but a switch is a switch. If you have a heavy ring of keys hanging it, it can wear the key switch contacts so that they become intermittent. You can try lifting up on the key, in the on position, to see if anything changes, to diagnose the problem...
