Why is my Nexus 5 rebooting itself for every half an hour

Recently my nexus 5 has started to reboot itself very frequently. Sometimes, pressing the screen lock button lightly reboots it. Current android version: 5.1.1

Welcome to Android Central! The Power button might be faulty--bring it to a repair shop to check it.

I had the same problem, try to block the screen auto rotation, keep your phone in portrait mode. It worked for me, no more reebooting..
