Wilma has only about 55K miles on her. 2008 Limited automatic. She would die after coming to a stop after being driven for awhile....then restart after sitting for awhile. We had a new Bosch CPS installed + the cocky young mechanic also attempted to re-solder the RCM.
The mechanic has had it for 3 weeks & is giving up. We're going to have it towed to another import shop as although it was driven 35 miles to this mechanic it will no longer start.

What's the next most likely failure / fix?
