I have a Scott, Kohler Command 17.5 riding mower by John Deere that always starts but recently it will not keep running. It seems like its starving for fuel or that something is interrupting the fuel flow. I can usually get it to work long enough to get through one acre but yesterday, no matter what I tried, it wouldn't stay running for more than three or four minutes. If you could share some ideas I can probably find the cause and fix it but I am currently at a real loss.
