Sorry, here's the symptoms: This has happened 4 times in the last 6 months; Starts and drives normal, after 10-15 mins. engines shuts down no matter what speed. Try to restart and NOTHING happens when key is turned all the way to the START position. All gauges and normal warning lights come on in the RUN position. Will crank and restart after waiting 20-30 minutes. Dealer is unsure what to do as there are no fault codes and since this is so sporadic they have yet to get the car to reproduce the shut down. I have tried to restart with both keys thus eliminating a keyfob being the cause. I thank you for any input.
