Small Engines (Lawn Mowers, etc.): Craftsman 6.5HP wont stay running, spark plug, air filter

Question
John - I've got a Craftsman 6.5 HP mower that stalls out after about 30 minutes of use and won't start again until the next day.  The spark plug, air filter and oil have all recently been replaced.  Any suggestions?

Thanks.

Answer
 Hello Mike:

 Use the Mower Again. When it Quits, Check for Fire at the Plug. If No Fire at the Plug, then The Ignition Module/Point Set needs to be Replaced. The Ignition Module is Part of the Coil on Most Models. Hope this Helps. Let me know what Happens.

 Good Luck

 Respectfully

 John
