My 4 year old Toyota Prius lost engine power on the freeway on two separate occasions. Driving in stop and go traffic on freeway I heard one beep as the car lost engine power slowed down and went to battery. A long row of warning symbols, starting with the triangle, lit up. I slowly exited freeway on battery power then turned car off. I restarted car about 15 min. Later and engine started, only warning lights illuminated were red triangle and check engine light. Dealer replaced inverter pump assembly and flushed the inverter system. 5 days after repair, while exiting freeway during normal traffic, beep sounded and engine shut off and the above order of events happened again. This time dealer replaced inverter assy (assembly?).
