Doesn't matter if I let it warm up for 3 minutes or 30, I've had it happen after driving on the interstate for 30 minutes as well as just around town. Have learned not to trust it. Just saying.
Right there with ya! My '17 has the same issue, but never know when it will happen though. Never chance it now, changed driving habits to never risk it! Terrible to say but don't like the odds! As you said, enjoy my life too much. Can't really find a common denominator to when it does happen.
2017 Lariat 23,576 miles so far. At 6,236 miles Check engine light and Service Electronic Throttle Control System which put the truck into limp mode. Had to drive it home with no turbo about 100 miles. Supposedly software update fixed it! Then again at 17,197 check engine and ETC again! Can't...

Just dropped my 2017 ED with 6252 miles at the dealer with the ETC code in limp mode also. Code showing Turbo under boost, Service ETC and needs two software updates. After reading through this thread I hope its not a sign of things to come.
