John Deere LX 188 running problems..HELP

16 years ago

I have a JD LX188 17HP FD501V Liquid Cooled Kawasaki Engine that runs great but dies after running for an hour. If you put the choke on it will run but will die if you try to put a load on it. I have put a pressure gauge on the fuel line after the fuel pump and i holds 6.5 pounds. Yes the cap is venting ok. If i let it set for 30 minutes it will fire up and go to running great again. I have seen others post with the same problem. Could it be possible the ignitor is getting hot and does not put out enough spark to fire the engine under a load?

might try checking to see if you are getting a good hot spark right when the engine quits - quickly remove plug, hold plug anode end metal prong touched to engine casting with pliers, have someone in seat try to start. You should see a bright bluish white spark. A yellowish weak spark or none at all is a definite problem clue.
