Interesting thread. Very similar problem has been bothering my car for the past month and a half. Seemingly randomly will go into limp mode, giving a gamut of DTCs each time. I can use HPT to clear them out and everything is absolutely fine for another day or so, then CEL comes back on, then a few days later it will drop to reduced engine power mode.
Dealer diagnosed it as a TB problem, but only did a cleaning and it seemed fine for a week or so, then problems started coming back.
If I have the laptop with me, I can clear the DTCs out on the fly for instant gratification, but I always try to get the ignition shut off as soon as possible when it goes to limp mode. If it sits for a while (as short as 10 mins) it will start back up in normal power mode.
Here's a DTC dump from HPT, which I collected the last time it went into reduced power mode:
[] P0121 - TP Sensor Circuit Insufficient Activity (Old) (Immature)
[] P013E - HO2S Delayed Response - Rich to Lean Bank 1 Sensor 2 (SES) (Old) (History) (Immature)
[] P014A - HO2S Delayed Response - Rich to Lean Bank 2 Sensor 2 (SES) (Old) (History) (Immature)
[] P1133 - HO2S Insufficient Switching Bank 1 Sensor 1 (SES) (Old) (History) (Current) (Immature)
[] P2135 - Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation (SES) (Pending) (History) (Immature)
[] P014A - HO2S Delayed Response - Rich to Lean Bank 2 Sensor 2
[] P1133 - HO2S Insufficient Switching Bank 1 Sensor 1
[] P2135 - Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation
[] P013E - HO2S Delayed Response - Rich to Lean Bank 1 Sensor 2
