Why does my LG G3 (D851) boot to the logo and then a blue only to turn off?

586-556-1400

    Just today my phone turned of while shopping with my wife, my phone was in my pocket. I tried to turn it on and it would not. I pulled the battery and replaced it, the phone seemed to boot fine. Now when I tried to boot my phone it boots to the LG Logo and then immediately to a blue screen, it just turns off after this. I'm at a loss of what to do next.

     

    My Phone;

    LG G3 (D851)

    Android 6.0 (upgraded within the last few weeks)

    Phone is completely stock. I've only installed apps and games from Google Play
