Vapor lock..........common, especially with todays fuels.........
Running a good un-oxygenated fuel or a race gas/9x combo of fuel may minimize it......eliminating the mech. fuel pump and using an Electric at the tank with a return line may minimize it.......running a Cool can to keep your fuel temps a little cooler may minimize it......insulating your fuel lines may minimize it.......
Notice the word MINIMIZE..........you may never cure it completely.....clear that hot fuel from the carb after idling for long periods by reving the engine a couple times...........
