it only happens when it is hot but I’ll be driving and the engine will just die. Everything thing else still has power, I will restart it and it will run for a few seconds then die again. If I leave it over night it will work good till it warms up again. Anyone have any input?

I took a look at the fuel pump driver circuit wiring diagram for your year. If you don't understand dc electrical, including reading wiring diagrams, have the necessary electrical test tools, you have three options.
First is to take it to someone who does.
Second is start tossing parts (can get expensive).
Third is learn dc electrical and get the needed tools.
If you go with the 3rd option, you should get the factory service manual on dvd.
Possible causes:
Failing connections in the circuit - there are quite a few
Failing BCM (body control module)
Failing Fuel Pump Driver Module
Failing Fuel Pump Assembly

I had a Honda that had a bad fuel pump relay that did the same thing. When it was hot, no fuel. It seemed to be the solder joint, but it was easier and gave me a better peace of mind to just replace it. This type of issue could be anywhere is the problem.

The only on-road breakdown I had with my '07 Expedition was the fuel pump. Died at highway cruise speed -- felt like the rev limiter on another car. A few minutes later the car would start and run and then an hour later it'd die again. Didn't know it was the fuel pump until I got it towed to the Ford dealer. There were some wires shorted together but not all the time. Don't recall if the pump had to be replaced or just the wiring repaired.
BTW, this was in the dead of winter.

Bringing this thread back to life as we're currently fighting with the same thing that has decimated our family vacation. Did you ever find the problem? We had ours towed to a dealer that replaced the FPDM and high pressure fuel pump, but had the same problem in the heat about 150 miles later. Looking for solutions as we need to tow our travel trailer back to Canada in a few days in 90-100 degree heat, and the dealer just wants to throw parts at the problem.

Have you checked the inline fuel filter? if it's getting blocked it will usually let enough fuel to pass to start the engine, but will then cause the engine to die as it can't pass enough fuel to keep the engine running. If you leave it for a while, enough fuel leaks through for the engine to start again. The filter is NOT in the fuel pump, so changing the pump does not help the issue. I would suggest changing the filter as a first step, they are not expensive and you can do it easily at home or at the side of the road if you have the pliers to release the quick connects on each side of the filter. It could also be water in you gas tank, as it gets hot, water expands and could be getting to a level where the fuel pickup is sucking the water from the bottom of your tank rather than the gas that will be sitting on top of the water!! unfortunately I don not know a way to remove the water from the gas tank! There are some additives that I believe allow the water to bond with the fuel so it gets sucked up with the gas and the engine still runs (just less efficiently), maybe a ford dealer has a tool to suck crap from the bottom of the tank and could check yours to see if there is water in there!!

It seems to run perfectly fine until it just kicks out suddenly. It has only happened in high temperature weather, which makes me think it's a component vs. heat problem. I'll maybe ask the dealer to replace the filter since it's with them now, but the P0627 code seems to suggest an electrical issue.

As I noted previously my problem wasn't solved until the fuel tank was dropped to access the fuel pump which revealed the wiring fault. Repair was quick after that.

2015 Ecoboost - Fuel Problem
We were towing our travel trailer in the USA (from Canada) and suddenly lost all throttle in South Dakota. 3.5L ecoboost, 135,000 miles on it. We ended up with three codes - P0627, P0087, and P00C6. We had it towed to a nearby dealership that said the FPDM and the high pressure fuel pump needed...

The 2015 Expedition does not have an in-line fuel filter, separate from the in-tank filter sock.

I have a 2010 and it has an inline filter so I assumed all models did, sorry for the misinformation..
