Randomly shuts down. Display says "starting disabled".what is causing this?

Yes. Most recently was last night. I was driving home from an event 30 miles away and was about 1 mile from the exit into my home town so I had been driving for about 15-20 minutes at a speed of 70 miles per hour. I was not using the cruise control.

Now does it start back up ok? While i agree it is going to have to be scan tested to find this trouble, i think the stalling issue is in the power control system!
