06 Charger problem?
This is called "Limp mode" its when the TCM see's something it doesn't like (engine over reving, tire speed not matching calculation, changed gears, etc) it shuts down causing you to restart the car. I have a 06 charger as well and have out differnt gears, trannys, drive shafts, engines, TCM, and PCM in it... What a PITA it is..lol.. But if your wifes car is stock and it hit limp mode and she turned it off then back on and it works fine then I wouldnt worry one bit about it.
