My cart won't run

My 92 club car gas cart runs great until u stop then it will not crank back up til it sits while.I changed plug .carb.at a stopping point. Seems like if the coil is getting hot it would die when it got hot but I run it 2 hours non stop and it will not quit.it's when u stop it won't restart.I've rum it 15 min or 2 hours it's the same ether way.any input would be greatly apreciated...
