Runs until hot and then quit

Here's what happened to my LT180
the tube inside the fuel tank was the issue.

I once worked on a swather where the owner had left the fuel cap off for a while. You would be swathing and the motor would randomly stop. Here it was several dead moth's semi floating around in the fuel and every once in a while one would end up over the fuel exit in the tank. The motor would stop and within a few minutes you would be able to start it again. It took me a while but I figured it out. So as someone already mentioned make sure there is fuel flowing right after it stops just to eliminate that issue.

Also it wouldn't hurt to make sure the coils are getting power right after the motor stops.
