Vapor lock anyone ?

[slugish]

Trying to solve a problem thats driving me batty.

Any of you had any problems with vapor lock , or gas getting too hot because fuel line too close to headers etc. Have talke dto Summitt tech & a lot of others & my problem seems to be vapor lock . Have any of you wrapped your fuel lines with heat tape or header wrap & did that solve problem. Cant beleive Im the only one who has this problem. Will run good for a while , let it sit for a while , try to ctrank it & no go -- starter turns it over but no go . Will eventally start & run ok till it happens again / have been towed 3 times because of this problem. Thought I miight be fowling plugs , but SUMMITT TECH SAID if pliugs were fowled , probably wouldnt crank no matter how long it set. . ANYBODY?HELP
