Ok here's a little update on my situation. Performed update today, set display timout to 30 secs, set security pattern to when display turns off, turned data back down to 15 minute timeout. Phone restarted after 5 mins of being in sleep again. So update did not fix my issue. Guess I'm waiting till the 3rd and keeping my phone either awake or on a charger till then. Thankfully it didn't enter into a looping reboot and I didn't have to spend a couple hours setting it all back up via factory reset. I will continue trouble shooting to see if I can narrow it down from display off, security settings or data timeout.
