So I did everything possible and the ball is now in Apple's court.
Restored iPad Air 32GB WiFi
Setup as new
Ran fine for about 48hours and then boom did a soft reboot
Erased two apps that I was using during the incident: crash log showed Hero Academy so I deleted it and I was playing Settlers of Catan HD which I was also playing before I did the restore. So I erased that too. Hero Academy was my first experience with it since the restore.
After deleted I reset my settings.
So this is a test to see maybe if those apps may have triggered the issue.
Based on what I've read this issue is more of an iOS issue and might be linked to safari and the iTunes Store app. Which both I had open at one point when the last reboot occurred.
Perhaps my experience can help others. I was told by AppleCare to hold tight for the next iOS update. So hopefully this issue will be resolved with a new update.
