Sounds like you nailed it.
Dose sound just like a bad TPS.
I had the same symptoms about a month ago. My wife had my truck and called me saying the truck is running but nothing happens when hitting the accelerator.
Had her use the high idle tune on my dp to get to a parking lot where i arrived with a new pedal saaembly. Installed in in the parking lot and boom fixed !
I had bought the pedal assembly 3 years back thinking i had a dead spot in the pedal but turned out it was another issue. So i took the new one back out installed the old one and kept the new one on the shelf.
IIRC you can just buy the sensor and pull the pedal assy out and install a new one. Some have luck pulling the assy out and cleaning the sensor using electric cleaner.
Depending on the year some have a integrated IVS and TPS and some the TPS and IVS are separate.
Mine was separate so upon removal 2 plugs (TPS and IVS) and 3 10mm bolts and she comes right out.

The TPS is simply that a pot. And the IVS(Idle Validation Switch) is the switch simple N/O contacts that allow the pot to be interpreted when closed.

Three bolts (Actually nuts) and you can remove it from the floor to look at it closer.
Compressed air usually knocks out the dust and dirt that interferes with the operation of the Idle Validation Switch (IVS).
Then put it back in and see.
Costs you nothing to try, and it usually fixes the condition.
