this may be a little tin foil hat..........
Due to the fact that there is so much high voltage moving through the area electromagnetic radiation could be the issue. There may be an issue with the shielding on some crucial eletronic componant on your truck or a componant in the PCM that is slightley out of spec and is being affected by the EM.
this is really out there but.....
I woud experiment by first placeing a ferrite bead around the wireing as close to the CPS as possible then make a pass through the area. If the problem persiste then place and additional bead aroung the wiring at the ICP sensor, if problem persisted then a bead around the wireing leading to the IPR, if problem persisted ( here it comes) try wrapping the PCM in tin foil or copper foil and grounding it ( the foil). The grounding isn't absolutely necessary but does/can improve the performance of EM shielding.
I know this is all way out there but how likely is it that your truck keeps breaking down at the same spot..............................

Steve's got a really good idea with the ferrite beads. I almost wonder if there's not a defect in the ICP you put on that's allowing RFI/EMI. If a ferrite bead helps it, I would suspect a faulty part. It shouldn't need ferrite beads to work right. I would also offer that if you do in fact resort to shielding the PCM, I would also try the IDM since it communicates with the PCM over a serial data link, and you DO want to solidly ground any shield you install. The shorter and thicker the ground wire, the better. The idea is to provide a very low impedance path for any intercepted energy to flow off to ground.
Have you noticed any strange lights in the night sky over that intersection? Any zombie activity in your area? Just wondering.

What are and where could a guy find ferrite beads? From the main kill spot there is also a radio tower to the south east and if you head south west a few blocks, that's the school I go to. South east of that is the huge radio tower and radio station that completely killed my truck. I did notice the seal at the back side of the IPR plug was looking corroded, gonna replace that too.

Ferrite beads are, well, beads typically made of powdered iron. I would try Radio Shack. They have three different sizes of "split" beads. Part numbers 273-067, 273-069, and 273-105. These come apart so you can put them around the wiring without disconnecting anything. The idea is that any interfering electromagnetic signal that would otherwise induce a current in the wiring will cause an opposing magnetic field to be set up in the highly permeable powdered iron bead, which then cancels the interference. again, its a troubleshooting bandaid, but they're cheap and easy, and may lead you to your culprit.

Still no luck. Haven't yet tried the beads but I have searched and searched with no gains. Still waiting on my buddy to get into town, such a good friend it takes months for him to drive 45 minutes.

A few weeks ago I started having an issue with my HID headlights. When I turned the lights on, the truck would die or stumble. Others reported similar issues with RFI from their HIDs.
So after reading about Ferrite beads (or RF chokes) I gave them a shot. I got these: FERRITE SPLIT BEAD, 7MM I.D. | AllElectronics.com and clamped one onto the wire running from the PCM (TS chip). So far, so good. I've added another bead 'just because'...
So, maybe a few of those are worth a try? Maybe put one around the wires running to the IPR solenoid? Maybe one on the CPS pigtail?

Truck Dies
I had almost the same problem. When it rained and I turned on my wipers the truck would die with each stroke of the wiper blade.
Turned out the cps was picking up interference from the wiper moter.
I changed the cps next to the road and it fixed it.

I had the same problem for a long time with my 02 7.3. I saw on facebook while ago where a guy was having problems with a CB radio causing interference. Someone suggested unplugging the ICP sensor and trying it. So I figured I'd try it to see if it fixed my radio tower interference problem. It worked! Plugged in, the truck spit and sputtered and even shut off if I was close enough to the tower. Unplugged I had no problems what so ever. I noticed it had a new ICP installed when I got my truck so I assume the previous owner used a cheapo parts store ICP. I'm going to get an ICP from the Ford Dealership and hopefully it will take care of it for good.

Keep us informed. It will be interesting to see if the new pigtail will
not also pick up the RF interference. If it does still do that then some
RF choke colis or a ferrite ring on the lines to help block the RF.
The only problem with the ring is you will need to make a loop or two
with the lines to get it to be effective enough.
One other option is contact the tower operator and ask for some help.
If they don't want to help maybe Uncle Charlie aka the FCC is also a option.

A new OEM ICP from Ford/International alleviated the problem. So if anyone is experiencing any kind of radio or frequency interferrance from CB's, towers, HID's, etc... Spend a little extra and get an OEM replacement ICP, its worth it.
Part Numbers:
Ford ICP = F6TZ-9F838-A
International ICP = 1807329C92

Just read this thread. Even though it's old we are having what appears to be the same issue. F250 SD, 7.3 Diesel, 160K miles. We were traveling from California to Virginia and passed thru Butte, MT. Came to a stop sign headed south on Alaska St at Granite St. Truck rough idled and died. Coasted across Granite St to the east. Truck started. Ran fine for the rest of the evening. Next morning we drove the same route and truck died again at the same stop sign. Coasted across the street and restarted. Ran fine the rest of the way to Virginia. We're gonna try the recommendation fora replacement ICP. Had been thinking about shielding and a local Ham outfit. Thanks for the insight.
