I went from Iowa to Colorado in my Jeep,(hey, it's got a Ford motor!) And didn't have carb problems with elevation until I got past 8500 feet. That's when I got rid of the Holley and went Edelbrock. Their bowls are on the sides not front-rear so not a prob. of fuel sloshing around while climbing. Also easier to change metering rods.
I'd rule out the carb.

JPB,
If i had to guess, i'd say your truck runs lean, overall. What kind of mileage are you getting? Does it run hot at all? Is it hard to start when the motor is warm?
Consider richening your fuel mixture.

It fires right up when warm and always runs below the halfway mark on the temp guage. I have a little black soot in my tailpipe so If anything I think the truck runs a little rich.
also fuel mileage is pretty poor.........10-12MPG but..........I do live in the mountains and drive nothing but mountainous roads. The town where the engineering firm that I work at is about 1500 or more feet lower in elevation than the town where my house is. So I drink gas no mater what car I drive.....

Well the missing came back while climbing a hill this morning.........
I'm starting to see why people buy new cars!!!!!! especially since I am just getting over the flu and really don't want to work on the thing.

New cars will strand you by the road even worse. At least with these old beasts you might be able to get it going again. The new ones are a pit of snakes and complicated as hell with all kinds of stuff that can, and does, go wrong. Imagine trying to diagnose a problem with the fuel system on a new vehicle beside the road. If the computer decides the engine is not operating properly it shuts down and you can't change it's mind unless you use a big hammer and get a new one. Are you beginneng to get the picture?
With all of the aftermarket ignition parts it is pretty hard to test anything or figure out what might be wrong. With the OEM stuff we can kinda tell...

My feelings exactly Eric. I use a leatherman tool for most of my roadside repairs in my trucks. That's usually all I need to get home. I do have a later model vehicle for daily driving to save gas on my long commute but when I really need to rely on something, the old Ford is the solid choice.

...what I love to see is when others make fun of my old Ford then have to call me to help them with their new cars, or take them to the dealer....

jpb, what I reading from your posts is that the problem goes away when you change the fuel filter and resumes later. If the fuel filter does make a difference, then I think you need to consider that you might have bad fuel or alot of debris in the tank. You might want to pull the tank and flush all of the crud out.

It behaved better after I cussed at it for a while.............
Actually I filled up the tank, it was almost empty so I am thinking that I sucked up a bunch of junk and clogged up the filter. also I noticed that the gas cap had a lot of suction so I could need a new gas cap that vents properly.
