Welcome to Android Central.

If you're using a microSD card, consider unmounting and removing to see whether that fixes it.

Also, Safe Mode may be worth trying, to test whether a third-party app is causing trouble.

A Cache Partition wipe may be worth trying.

Please let us know if those things don't help, or indeed, if they do.

It could also be something as simple as a bad power switch or an intermittent short where the power switch is soldered in.
