The tcs off and slip lights after a noticeable miss while accelerating, the vehicle fails to accelerate when the accelerator pedal is depressed, and then the vehicle stalls, regardless of traveling speed, resulting in total loss of power steering and power braking. after stalling, the vehicle sometimes will restart on first attempt, other times it takes a few tries or turning the key to on position for 5 seconds and then turning it back to off, repeating 2-3 times then starts.the problem is persistent, the vehicle continues to fail at random almost every time it's driven as short as 1 mile distance, but has also been driven 20 miles without failing. while driving a daily route, the problem often occurs at a common location, whether related to distance, terrain, or coincidence is unknown.
