A spider in the tank story.
Interesting theory about the truck. Is this hill steeper than anything else in the area ? Could the 'miss' be caused when the truck is under more load and demanding more fuel. You need to find a similar grade hill and test it on that, if it is indeed steeper than all those around.
There was an fuel advert in the UK that stated, 'Put a Tiger in your tank' There was no mention of a spider.
I've had similar difficult problems to deal with in the past, one bizzare one was due to a dead spider ! When the vehicle was 'missing' we would prime the fuel filter and it would clear for a while, indicating a lack of fuel reaching the filter in the first place. So we then temporarily by-passed the fuel filter using an old clean jug containing fuel and put the fuel lines in it and started the engine. We discovered air was being introduced to the fuel before the main filter and pump. After dropping the tank and removing the fuel lines from the fuel pick strainer and putting them into another clean container of fuel and starting the engine, the air cleared from the other end. We removed the pick up pipe/strainer from within the tank and gave it a quick blast with an airline and out popped a big fat spiders body. The body had been partially blocking the fuel pick up pipe in the tank and disturbing the fuel flow not allowing enough fuel through on high demand and introducing air. This was after lots of work including checking injectors visually and changing filters etc. I doubt yours is a spider [;-) ] but sometimes after a lot of time and expense it's a 'foriegn' object that is obvious and simple when found. Although I would have thought that a sensor on a newer vehicle would pick up on poor fuel delivery, but it may not and sometimes the old fashion way is better than computers, just like mapping I guess.
Good luck.
Afterthoughts.
It might not just be the gradient of the hill, but the duration of it and how long the demand is on fuel. How about simulation ?
I would be surprised if it was anything to do with the towers, especially as you have experienced the problem prior to this. One way to try and test your theory is to come down the hill in a lower gear and use the throttle to gain speed, you should have the same symptom almost immediately if it was electronical interference.
In a similar fashion for fuel delivery/demand, if you used a lower gear [to save a speeding ticket] and similar throttle input to that of going up the hill for the same amount of time on a road away from the towers, would it do the same ? [Yes it will work the engine harder for a bit]
Yeah I'm a little crazy in my methods, but undefeated by a vehicle ! lol
Nothing has changed .... and a simple solution.

Get a walking stick.
Ever since I have had to use one, I have not been offered anything but a groundfloor room.

All that and the One Horse Motel too!
Sorry to hear about the heel spur issue. But very glad you had nice weather for the the pass.
