I have had a few problems with my 2005 5.4 SCREW lately. It seems like after a drive, shutting it off, waiting a few minutes, and then it wont start. After waiting a few minutes, and cycling through the ignition it finally starts. Any idea of whats happening? I have been told by the dealer that my battery is going bad, but I don't understand why waiting a few minutes and cycling the key helps.

 

Anyone have any ideas?
