First weird thing coincidence maybe... But kept trying to die plowing snow then reved high so had to shut it off, started back up ran fine then dies twice more but would start back up after it cooled off a few minutes

 

First thing on any 2 stroke when this happens is to do a compression check.If a 100 psi or less,the rings could be loosing seal against the cylinder walls when hot and die. If allowed to cool down then they may crank back up and die again when hot. It also could be spark problem or fuel flow could be restricted either from the fuel valve,fuel tank vent kinked,etc.Other things to check since you said it revved high is the carb itself,intake manifold for cracks or possibly crank seals,mainly the one behind the drive clutch.Just a process of elimination until you find the problem.
