I have a 3 year old Ariens MaxZoom 60" Zero Turn and it cranks but won't start after the initial start and run for about 15 minutes. Is there a heat sensor on it? If so where?

Nope. I suspect you have an ignition breakdown issue from heat. Try checking for a spark and diagnose from there.

Thank you for your response. After about 1/2 hour it cools down and will restart and run for about another 1/2 and stops again.

What SidecarFlip is saying is that you have to check for spark when it dies...
When it cools down it's too late...problem clears itself.

Also check that you gas cap vent is not plugged.
Loosen it some and seem if it will mow longer than 30 minutes...
Of course if tank is too full it could leak out....not good

Have you ever removed the blower housing & see if the cylinders are clean & free of grass or mouse house debris ?

Thank you and yes this has been done.

Your problem could be electrical or fuel related
SO to cut down the possibilities arm yourself with an inline spark tester like the Oregon 42-087 and a spray can of carb cleaner.
Fit the tester & go mow, while the engine is generating it will glow red.
If it stops glowing red before the engine cuts out you have an electrical problem, most likely the magneto coil
If it glows red, then starts to flash as the engine slows down to a stop you have a fuel problem.
Quickly squirt a SMALL SPRAY ( less than 1 second ) of carb cleaner & crank the engine.
If it starts up then that confirms a fuel problem

You can the start to isolate the problem as previously mentioned by loosening the fuel cap.
If you hear a sucking or the mower starts right up again, new fuel cap time
If not then you are looking at a blockage somewhere between the fuel outlet in the tank and the carb float bowl.
