Answer
 Hello Pete:

 Send me the Model Type and Code Numbers Off the Engine, Please. With these I can Locate a Breakdown/IPL and Better Assist you. However, it May be the Valves Require Adjustment. If the Engine has Fire after it has Gotten Hot and Quit, then Check the Gas Cap and Ensure it is Venting the Tank. Change the Fuel Filter. The Valves are the Next Item to Check. The Intake Valve is Set to .006in and the Exhaust is Set to .008in -.010in. Hope this Helps. I am here if you Require more Assistance. Thanks.

 Good Luck

 Respectfully

 John
