Need your help...My 2003 Ford Expedition XLT has begun stalling at normal speeds (50-60mph), and also while idling. When I am driving along it suddenly feels like it isn't getting gas, and it will "kick back in" or it eventually stalls. Sometimes the truck restarts right away, other times it takes several attempts to restart the engine. However, no codes have ever shown up on the computer. The truck was taken to the shop where they let it run until it "died" and were able to get a fuel pressure reading and ended up replacing the fuel pump. However, despite that repair the problem persisted and the car went back to the shop at which time the shop couldn't get it to stall so they replaced some relay switches and cleared the computer. Well, I just got the car out of the shop and you guessed it...still having the same problem...Anyone have an idea on what the problem is? I really love my truck and don't want to have to trade it in. The mechanic is concerned because to date a program code has yet to show up.
