Engine stall at speed- no code

[R0cketMan]

I had the same issue in my '03. I'd have the cruise control set on the highway then the engine would cut out. Cruise control sent the pedal to the floor, no check engine lights. I'd have to put it in neutral then restart. Turned out to be the fuel pump relay in the passenger side fuse box. The relay had a hole in the side of it. Infamous problem because Ford used a 10amp relay (Omron part number F8VF-BA). I bought a 30amp replacement that was used in the updated fuse panel assembly (Omron G8QN) from eBay for $9 and soldered it in myself. Saved me $400 by not needing to buy the whole fuse panel from Ford. I haven't had an issue since I put the new relay in! Fuse panel can be removed in 30 minutes. It's a good quick check if you've run out of other options.

This may sound silly, but did you check the battery cables? I had the same problem on my expy and it was corrosion on the cables. Same thing happened to a friend in his Nissan SUV... I cleaned up the terminals and no more issues.

Remove the negative battery wire for 5 minutes. That may erase any glitches in the microprocessor. Tghen reconnect it and road test.
When's the last time you changed the fuel filter?

A 10 amp fuel pump relay? I didn't think they made relays that small.

Hey there!
Late thanks for the details!
I finally got around to this today and was relieved both when I saw the condition of the relay was as expected (hole blown through the side) and upon hearing the engine roar to life after completing the job.

As always this forum saved my bacon and a good chunk of change!

Thanks again!

I have been having same issues that all started 2 weeks after my tranny rebuild. (May-2019) found my Negative battery terminal loose. but pulled the fuse panel to check, and the relay was fried, with a hole in the side. So far, i replaced my fuel filter, the relay, then the fuel pump... 3 weeks ago, now having same issues... Going to pull the panel again and re-check the board tomorrow.

Does anyone know if a crank sensor could cause an engine shut down while driving?
Only because it is located near the front drive shaft which has to be removed to remove the transmission.

The crank sensor is kinda buried behind the AC compressor. I don't think any work done on the front driveshaft would interfere with the crank sensor. A bad crank sensor will kill the engine but will usually throw a DTC code ( P0335 ...). Whereas the fuel pump quitting will not.

But here's a good YouTube video that 1A Auto put out on the Ford sensor if you're curious:
