Possible Vapor Lock

Could somebody help me fix my startup issue. Car runs perfect. It's only after it heats up after only 10 minutes if I turn it off to get gas or chat up a friend, when I try to restart it, it cranks 30 times and then starts up. Could it be possible to have vapor lock with an electric fuel pump at 7 bar? I suppose if the line is close to something hot, it's burning up the fuel before it reaches the carb, until it cools down enough to pass the vapor lock in the line. Please help me understand this. Should I follow my pump from the fuel tank to the carb and look for hot spots? This is a consistent issue that can be reproduced each time I drive.

Thank you
