Sounds like TCS fault is putting the car into limp home mode. My understanding is that the aftermarket TCS disable switch will disable TCS, but cannot prevent the car from going into limp home mode when a fault is sensed. I assume you see a TCS warning light when this happens. Also check engine light will flash a fixed number of times (code) when key is moved to ignition position. Most common cause is Electronic Throttle Body ($$$), but could be the pedal potentiometer or safety switch also.
