Sick profiler2 - Measuring values freezes and restarts

We have a Sick profiler2 a 3d laser profiler vision sensor connected to a pasting robot. We recently have some problem with it. Sometimes it stops measuring suddenly and its display values freezes and if we connect to it by programming cable and want to see the camera view it is restarting.
I factory reset it totally and reprogram the setting but the problem still happens. Any idea?
Thank you in advance for your help.
