B 7610 kubota tractor

[hpriddle]

My kubota B7610 tractor is hard to start and when it does start will run for only a few minutes. It was suggested to add 911 diesel additive, which I did to no effect. I put new fuel, air filters, fresh diesel fuel and the problem persists. It has 190 hours on it and it is garaged. The dealer is far away and I'm told very expensive.
Any help would be appreciated.

Does it turn over? Are you using the glow plugs before you try to start it? Does it just die all of a sudden or spit and sputter a bit? When it does start does it run on a couple of cylinders, then run on all 3 and then die? Did you drain the fuel completly out of the tank and put in new fuel? Did you put on a new fuel filter?..........This is only the beginning of trouble shooting.......At least none of the really know it all folks have come through telling you to change the spark plugs......God bless........Dennis

Does it only die in gear?
Does it throttle up right after it starts?

Sounds to me like a fuel issue, has it recently been ran dry? Could be air in the lines, to fix if its air in lines, crack injectors as helper cranks, bleed air out and retighten
