Moto x style start up issues

[Scott102 0]

This morning my moto x style randomly switched of at high battery charge, could not turn it back on again as it would not get past the start screen before switching itself of again after i try to restart it . Some of the time it would not even begin to start up at all. Occasionally i can get it to fully boot up, but after using my phone for a couple of minutes it just turns off again.

Is there any easy way to fix this, this problem was most likely caused by me having a replacement screen fitted to my phone the day before.
