Sounds like its heating up and stalling due to ring/piston expansion. Like its getting way to hot.
Then once it cools its runs again as the piston/rings have contracted.
Have you done pressure test on the cylinders?

Remove the Tstat. Put in a pan of water of the stove with a thermometer and see what the temp is when it opens. May not be the problem but at least you can rule it out that way.

Something is plugging the idle circuit in the carb. You may think its clean, but its not. It will run when cold as it is on the high idle circuit (kind of an automatic choke), which is injecting more fuel into the motor. As soon as it kicks itself off, it will die. Let it cool down for a few mins and it will start back up with the high idle again. Options are try to reclean it again or buy a new carb. New carb is still cheaper than a new motor. Good luck.
Hmmmm. Sounds like you know these engines.
My T8 trolls great but when I rev it up its wants to die. Ive cleaned it a couple times.

Check your fuel pump.
I spent 3 months chasing the same symptoms on my kicker this spring. Changed fuel lines, cleaned the carb multiple times, changed primer bulb, rebuilt the fuel pump, new plugs and wires. Finally took it to a shop, they cleaned the carb 3 times and even bored out the main jet because the only thing they could come up with was lack of fuel. Nothing worked. I finally decided a brand new fuel pump was the cure.....it was. I'm not sure why the rebuild kit didn't cure the problem but it didn't. Now my kicker doesnt idle quite as low as it use to due to a bigger main jet. :bash:

Wierd! Cause there aint much to the fuel pump. Its an easy no brainer rebuild.

Sure beats $350 for a new carb and 3k for a new motor... Ummmmm, motor not for sale anymore... :chuckle: :chuckle: :chuckle:
So check list went like this, new filter, new fuel pump, new fuel hoses, new 3 gallon single tank for fuel, carb cleaned three times, and new hose connectors... Hopefully she'll be good for another 1500hrs....

Might be a coil breaking down and losing spark and once it cools down the winding comes back together and has spark. See it all the time with small engines or maybe a vent problem.
My first thought.
