Small Engines (Lawn Mowers, etc.): riding mower stalling, proper manuals, safety interlock

Question
my riding mower shuts off when the engine gets hot? this happens when I engage the blades, it wont start until it cools down, I changed the coil and starter and it still does it! please help!

Answer
 Hello Pete:

 Have you Checked the Blade Safety Switch? Is there a Safety Interlock Relay? Send me the Make and Model Numbers Off the Mower and Off the Engine, Please. With these I can Locate the Proper Manuals and Better Assist you. Thanks.

 Respectfully

 John
