red charge light comes on when engine is dying out but goes away if engine returns to normal, could it be the PCV valve. I've had this replaced twice before.

    If the Check Engine Light/Service Engine Soon light is on or has been on a code is stored in the computer in your car that will indicate where the problem may lay. Stalling or cutting out may be caused by many things, a defective idle air control motor or vacuum leak are the two most likely causes.

    its not a recall but ford put out a service bulliten to the dealers, Its called the alternator wireing harness. If you follow the 1 of the two red wires that comes out of your battery one has a long black clip on it that says "fuseable link" just past this clip two smaller wires branch off. a short one that runs towards the front of the truck and a longer one that runs back towards the bottom of the battery, This longer one is resting on a aluminum AC pipe. Where the wire rests on this pipe, flip the wire over and you will see it is worn down to the bare copper threads, Tape it up and tape where it rests on the pipe or go to ford and order a new one, its a 10 min job you can do yourself. The part is under $40bucks
