just a update on my post from a couple of days ago. I thought i had found the problem. And actually ran the tractor for about 10 hours (moving snow). then the same problem started again. to update i have a farm pro 2425. i had thought the problem was a compression washer where the fuel line screws into the bulb assembly off of the tank. after the tractor quit i had thought that my make shift washer and teflon tape had failed so i replaced it. but it doesnt seem to work now. at this point i can bleed the air out of the fuel line start the tractor, the tractor will run for about 30 seconds then die. any thoughts on what the problem may be would be greatly appreciated. From what some of you folks said before, there is a screen that goes about 3" up into the fuel tank off of the bulb assembly. i am thinking that maybe this is plugged and pulling a vaccuum on the fuel line allowing air into the system. What do you think? any imput would be greatly appreciated. Also one other thing. I just bought a taskmaster titan. all the specs i read and dealer testimonials say this is a great tractor. what do you all think. Jake
