“While driving at highway speed in the left lane of a divided highway, the vehicle suddenly and without notice lost engine power and power steering. The weather condition was light rain and the road was wet. I was able to move over to the shoulder of the highway and restart the engine but it died within two to three seconds. I then restarted the engine several more times and was able to maintain a running engine after about 5 restart cycles. …”
