HTC ONE M8 on Build 10536.1004 - random frequent reboots

I'd appreciate some help as these reboots are depressing. I will list the solution I've tried below

1. Soft reboot

2. Reset in WP8.1 ( Settings > About > reset your phone)

3. Hard reset using Windows Phone Tool ( Rolling back to WP8.1)
a. Factory reset

4. Reset after upgrading to Build 10536.1004

Thanks in advance for your assistance. :cowboy:
