Ets dashboard light on 2000 Volvo V70 xc came on while driving approx. 35 mph. Car immediately hesitated and slowed to a speed of approx. 15 mph, then came to a traffic light and engine shut down. After several attempts to restart engine, it did start and arrived at destination which was car repair shop. Traffic behind vehicle was stopped while attempts made to restart car, amid much honking of horns and angry comments. On at least four previous occasions within two weeks prior to this incident, ets warning light came on, and except for one occasion when car stalled but could be maneuvered to side of road, engine hesitated but did not shut down. Hence the trip to the car repair shop on this date. As I write this, the ets system is being evaluated and the throttle body is being replaced.
