Random shutdowns, way too frequent

Question

I have been experiencing random shutdowns with my HTC 8x Windows phone for about 3-4 weeks. What can I do to resolve this problem?

Michelle -
I have had my 8X for 21 months. It has been a workhorse and I had not problems with it until about 2 months ago... when I began noticing that it was often off when I picked it up from my desk at work or took it out of my shirt or coat pocket. During the last 2-3 weeks, the phone turned off randomly many times per day -- probably 5-10 times per day.  It has shut off (I get the "goodbye" screen) during calls with clients six times in the past week.  That's a huge problem for me.  And, the Windows phone is very slow to reboot... which is even more problematic. These random shutdowns are not due to low battery.  They happen in the morning on a full charge just as much as they happen in the afternoon when power levels are lower. 
For many weeks, I have checked many times to make sure I have the most up-to-date version of the operating system.  I do.
I did factory reset yesterday (Saturday). The back-up restoration process went well.  Today (Sunday.. which was a low phone use day for me), I noticed it had randomly shut down 2 times.  Neither of today's random shut downs happened during phone calls.
I appreciate your assistance with this matter.  Is the problem the device or the network?
Thank you,
Eric
