 Reduced engine power/stalility control disengaged message displayed, engine went to idle and would not exceed 5-10 mph. traffic from behind served to avoid decelerating vehicle. i understand this is something that is somewhat common with these gm models. the possibility of rear end collisions may be experienced due to rapid deceleration due to loss of power. happened intermittently again during the day. it clears itself after the vehicle sits for a while but there is no warning when it might happen again. information received form various forums state it is believed to be within the wiring harness for the throttle position sensor.
