Small Engines (Lawn Mowers, etc.): honda, pressure washer, good luck

Question
i have a honda 9hp pressure washer. at idle it runs fine. at high speed its fine. after awhile it begins misfiring, and stalls out under load.  i believe my coil is heating up, shorting out and breaking down. what is your thought, and what do you think  i should look into?

Answer
 Hello Jeff:

 From your Description it Sounds like you have Everything Under Control. Your Description is that of a Coil Breaking Down under Heat. Replace the Coil/Igniter. Hope this helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
