Small Engines (Lawn Mowers, etc.): Honda IZY Engine cuts out, honda izy, carburator

Question
HI John. MY Honda IZY HRG465C1 PDE 4.5 HP lawnmower is about 4 years old. The engine has just started to cut out after running it for 5 mins. It will then restart but after a couple of mins will then cut out again. I managed to start it again a few times but againg it cuts out after a couple of mins. What is the likely problem and is their a manual I could follow if I need to do any dismantling and cleaning, etc. Thanks.  

Answer
 Hello Paul:

 First Check for Fire as soon as the Engine Quits. If there is Fire at the Spark Plug, then the Carburator May be Picking up Trash. Im Leaning towards the Carburator. Hope this Helps. Let me know what Happens, Please.

 Good Luck

 Respectfully

 John
