750 randomly turns off..

[Flip_Flop]

Why does the unit randomly turns itself off and sometimes turns itself back on again?
There is plenty of space on the card and it has recently been successfully used.
There is no indication of the power supply being interrupted..
Thanks in advance for any helpful comments.

Good evening could it possibly be a software update ? Do you update the firmware/software when needed? Do you format the SD card regularly, front or rear cam issue? kind regards Mark

Many thanks, Mark, for your quick and helpful reply.
The card was recently re-formatted so hopefully it is not that. Will check firmware update.
