Can happen 2-3 times at each account and drives me nuts. I have checked with my dealer (wonderful) but have come to no conclusions. First thought it may be water in the gas but has gotten redundant after many gallons thru. Think there may be a bad ground but do not know where to start? Any help would be great. '03 w/ 400 hours. 52" w Kohler 23. have not changed fuel filter yet.
