My 1998 4.6 will do this when it is time for new plugs and possibly wires. Your 2003 will have the "Coil on plug" or COP plug wire design and those are supposed to last a while. 1998 was the last year with the 2 seperate coil packs, and mine have been terrible. I got mine new in 1998 and have been through 7 sets of plugs and 4 sets of wires. Anyway, installing a new set of O.E.M. Motorcraft plugs is a cheap way to restore lost power, especially if you can't remember when they were changed last. Good luck, let us know what the problem was and how you fixed it.
