Vehicle lost power for 3-5 seconds at highway speeds approximately 65 MPH on three separate events. Vehicle slowed down due to power loss while in heavy traffic. Three other times at idle speed in drive and in park engine stalled and immediately restarted. Loss of power steering due to engine not running when stall event happened. I performed inspection of fuel pump relay which is internal to passenger side fuse block. Found inadequate solder joint on integrated relay printed circuit and burn marks on outside of fuel pump relay. Located salvage fuse block same make and model and inspected. Same damage on salvage fuse block assembly. Replaced with aftermarket fuse block with revised solder joint and updated relay.

While driving a 2004 ford expedition 178,000 kept stalling on the highway and streets. I had it towed several times because it won't start back on the next day it would turn on. Had the fuel pump replaced and still having the same problems it turn off on my 18 year old son like 5 times going to school and work where it almost got to the point where we felt it wasn't a reliable due the fact it stalls while on the road or even just turning and almost caused my sons life . Finally we found out it's the relay gets hot and it causes for the car to stop and I'm aware that ford knows about this very frustrating and disappointing they have not done a recall on this the relay can not be change by its self has to be the whole circuit board

The vehicle shuts off while driving (at any speed) and often without warning. In addition, the vehicle may also not start at all then start without explanation. The most common recommendation is to replace the fuel relay. To do so, you must replace the smart junction box/fuel relay panel. This appears to be a common problem with numerous mentions and is often difficult to diagnose and commonly becomes a process of elimination. The biggest concern is the safety issue and odds of accident or fatality. Diagnoses typically requires complete failure because the symptoms can rarely be duplicated. This has happened frequently with complete failure happening. Hardwiring the fuel pump rules that out. Fuel relay is found to be hot to the touch.

Multiple and intermittent engine stoppage. The engine stalls suddenly while driving in traffic causing hazard to self and others. Sudden loss of power steering makes control of vehicle difficult as power steering is non functional as you attempt to pull to the side of a busy road. Braking systems also are mostly non functional without the vacuum created by the running engine making it very difficult to stop quickly. This presents a dire emergency condition for the surprised driver, and a hazard to other occupants as well as other drivers nearby. A driver who is small in stature may be unable to man-handle the stiff steering condition. Once stopped, the engine may restart right away or not, stranding occupants in unsafe conditions and cause an accident chain involving life and death. Fuel pump relay failure is the cause and very common, (100s of thousands of posts online about this problem). This problem affects these expedition vehicles in a widespread fashion similar to the lcm safety issue with another ford product, the crown victoria. (a recall was ordered on this issue for some of the model years) this has happened to me 8 times in 3 weeks since owning this 2004 vehicle. It is currently at the ford dealer who state they may need to keep the vehicle for up to 3 weeks to observe the failure mode. (it is intermittent)
