HELP!! I need help . Starts fine, Idles fine, but when I put it in gear, it misses and dies. Was running good, got water in the fuel, changed both fuel fillers several times, drained off fuel, replaced with new , changed fillers again, still misses and dies. Can sometimes manage to keep it running till I hit a bump then it misses and dies. Any ideas what is wrong? I also replaced safety switch under the seat connected to the drive range. Possible broken wire ?????
