Moto G4 Plus frequent restarts

AC Question

My Moto G4 Plus is just two months old. It restarts on its own several times a day. Tried everything that their Customer Service asked me to do- remove all apps, factory reset etc. Finally took it to the service centre where they re-installed the software. My problem continues. Now I am getting only "Auto- replies" from Motorola, but no solution in sight. Can someone please help? The phone is good and my friends who has the same one has no problems at all. Thanks.
