Why does engine cut back, even though the mower still cuts well?

SOURCE: Craftsman 42 inch riding lawn mower is not cutting evenly

The first thing to check is your blades. If one is bent, it will never cut even. It happens a lot hitting roots, antbeds, etc. Mulching blades will bend easier than a straight blade. It's best to take them off and lay one on top of the other to see if they're bent.

it sounds as if your carb is dirty remove bowl on carb i"ll bet it's it's dirty if so you will need to remove the carb and clean it

SOURCE: when mower gets hot it cuts off crank back up run a min cut off

1 of 2 things happening
first change the fuel filter seams that the gas is vapourizing
If that does not fix it replace the engine coil as it heats up it is breaking down in voltage causing the engine to die

Check to make sure there is no obstruction in the blades or on top of the deck where the belt goes. Also check that your pulleys turn freely and that a bearing didn't freeze up.
Let me know if this helps.
