I have a Great 1996 2040. I was moving dirt and all of a sudden it died and the Brakes locked. It started right up and ran for a few minutes and did the same thing. Sometimes it would run for 1 minute and sometimes for 5 and then die. I decided that I should change the Fuel Filter of which I have not changed for awhile and it was it "Deplorable" condition. I got the filter changed and primed the engine and it started and ran for another minute or two and then died. I finally got it up to the Barn and checked everything and cannot find anything loose. I started it Sunday morning and it ran perfect for 55 minutes and died. I backed it in the barn and it died 2 more times. The machine has 1700 hours and I have had it for 4 years and has run perfectly. Any input. Thanks, Bob S
