"One of my 502's runs fine

"One of my 502's runs fine cold, but after I run it for a while and bring it down off a plane, it will idle for a minute or two and slowly decrease in rpms and dies, and wont restart. After I lift the sundeck and run the blowers for a while it will restart, but if I dont get it back up on a plane or get the rpms up it will die again Could this be a vapor lock problem?? replaced fuel filters that didnt help.???????????
