How do I stop my device from shutting down unexpectedly?

My Galaxy S5 is less than one year old.  Yesterday it began shutting down after about an hour.  Battery is charged and even occurs when plugged into charger.  It will not restart or open until I remove the battery, keep it out a few minutes, and then reinsert the battery.  It will then start normally. Later the same problem recurs.  Later, I installed successfully the newest software update.  The problem is unchanged.  I also know that the battery is warm after this has occurred. The phone has not be dropped or immersed in water or had other changes.  No new software installed that I remember recently.

Try doing a "Wipe cache partition"

Power off your Samsung Galaxy S5 by long pressing the Power
On/ Off button. Wait until the device is completely shut down. Now you have to
press the following keys at the same time to turn on the phone again:

Power On / Off

Volume up

Home button
If the Samsung Galaxy S5 vibrates once, release the power
on/ off button, but keep the other two keys from the key combination pressed
until a menu appears on the display.

Mark the entry "Wipe cache partition" with the
volume down key. With the power on / off button, the entry can be selected and
the process will start.
This usually takes only a few seconds. Then the previously
displayed menu appears again. Now select the first entry "Reboot system
now" and run the command again with pressing the power button. Your
Samsung Galaxy S5 will now reboot.
If this does not
help, you will then need to do a factory data reset on your Samsung S5 .
