well you could ride it for ten mins then let cool down for 5 then ride again, or you could try changing the choke and revs as they may alter the performance and if it is running too quick, it will get too hot too quick..... also clean the air filter as you might just have sum dirt in it and it might be blocking the carb up which would cut out the engine.... or unscrew the pullstart cover, and remove just the cut off switch lead as it might be short circuiting somewhere, but you will have to stall the engine to cut it out
