Just had the same problem with the so-called limp mode. The day before this happened, I had removed my air filters and washed them out (Nismo Cold Air intake Long tubes). I left them out to dry overnight and installed them the next morning. Went to the post office (Approx 5 miles), car drove fine. Left the post office after about 3 minutes and the car started bucking back and fourth when trying to give it a little throttle. Had to drive home at 20 to 25MPH, car would not go over that. Got it in the garage and tried to rev it in neutral...still would not rev. Car sat overnite, then started the next morning and took her out for a drive...and no issues. Car was fine. No DTC's, lights, etc... Only thing I can think of...is that the filters were not completely dry and she wasn't getting enough air, or somehow moisture worked it's way up the the MAFS and was causing issues??
