Turns out the dealer didn't have a new CPS, and didn't know when they'd be able to get one. Turns out I had a good used one from my 7.3L Powerstroke that fits and seems to be working fine. I've run the truck for a few hours since then and no hiccups so far.
Another thing that I think was related was an issue with the tach. There have been a few times over the last few months when it has given erratic readings, but the engine still seemed to run fine so I figured it was loose wiring in the dash or something like that. I didn't connect the dots in my head that this was probably also caused by the failing CPS.
