2005 F150 start problem

[boatingnole]

Every once in a while my F150 four stroke will turn over but wont fire. If I go and squize the bulb and then start it it will start right up. It only seems to do this if it has been idling for a while and then I shut it off. Any ideas? Does this engine have a electric fuel pump? It seems like it is not getting enough fuel at idle. Once it is running it will run fine.

May have a vapor lock problem, if it's a 2004 or 2005 model have your dealer check it to see if has a vapor recovery system on it.
