Who I have the same questioned this topic

I have a Moto Z Force phone my Motorola.  Mid January it began turning off when attempting to take pictures.  Even with the battery at 63%, just choosing to open the camera function shuts the phone down.  Does anyone know why this is happening?  The first time it happened after taking two pictures, did the same thing on another day and today it turned off as soon as I opened the camera to take a picture.  Is this a problem that I need to replace the phne because of it? Is the problem covered under the phones warranty?
