mx7 Board makes every 5 to 10 minutes restart

Good day community,
I'm busy working on a project with a Cerebot MX7 Pro. It's me now noticed that the board so every 5 to 10 minutes restarts.
This is not intended by me.
I would be happy to send you my project to be ruled by an error on the board.

I am using MPLAB X 3.15 with the XC32 1.40 on the PowerDebug USB connection.

I hope for an insightful answer or input.
