I had this same problem and in fact the motor would lope and stall. I had a crack in a coil pack and in fact, these were the original coil packs and I was able to secure an aftermarket set on EBay for a GREAT PRICE - manufactured for the 2003 Expedition - and it FIXED the problem. The crack was not visible and the mechanic explained that the truck would run until it reached a certain temp and then the coil packs were absolutely fouling. You might try this.
