Just had a another reply from powertrain programming engineer, and she states the P0121 is the code to go after.
When the PCM detects a condition within the throttle actuator control (TAC) system, other DTCs may set due to the many redundant tests run continuously on this system. Locating and repairing one individual condition may correct more than one DTC. Keep this in mind when reviewing captured DTC info.

She is also leaning toward a TP sensor, but could be a MAP sensor. She also states that it could have been what I suggested, "a brain fart," that may never happen again. Just a scenario where the inputs got slightly messed up for a second or two, and the PCM could not relate all the inputs. Restarting the engine cycled all back to normal, and the PCM shook it off and went back to normal mode.
