Kubota M105S Stalling out lossing power

[nk12054]

We have an Kubota m105s and keeps stalling out. In Feburary had problems with stalling and dealership came out drained and cleaned tank. Blew air thru fuel lines, Cleaned water Seperator, Replace fuel Filter. Ran good for a month then would stall after 30 mins of running for two days so shut it off and let it sit for a week and has ran good till now. Has 75 hrs since Feb. Yesterday we Changed Filter, Cleaned seperator, Blew air thru line going from filter to tank, and drained the left tank. Ran good for 2 hours. Started this morning ran for 10 seconds and stalled out and died. Restarted and ran good for 30 mins now stalling and lossing power again.

my 105 has starting to do the same thing i will start it up and it will slowly die in a few mins, then i will pump up the fuel pump and will run fine till i get a mile down the rd and it will start to starv fuel, if i downshift it willcome back to full power... im at a loss could you share with me what you found wrong..

Several years back I owned a M4900 that acted the same way. I found a small white screen in the water seperator housing that was plugged with debris. I removed tiny screen and fuel starvation problem was solved. I suppose you've checked to be sure tank is venting?

When it starts to act up, remove the fuel cap. Check for any damaged fuel lines.

Is there a self bleed lever? Check it is in the "run" position.
