Gary, I'm with you. There is nothing major wrong with that engine. Probably something to do with extended inactivity during non-use. It could be electrical(ECM), mechanical(fuel pump failure) or chemical(fuel varnishing due to extended inactivity)
While there are guys on this forum that can give you very good advice about your symptoms, you should also run the description of your problem by the folks on some of the many Ford specific sites. I,m sure there are others that have experienced your woes. Have a look here for starters...http://www.ford-trucks.com/forums/forum28/
