Why does my lg stylo 4+ keep shutting down and randomly restarting

[Android Central Question]

I can be texting or playing a game or even googling something and my lg stylo 4 will shut itself down and restarting. I have missed important calls because this phone shuts itself off.

lots of opportunities for this to happen.

is it still within warranty? then take it back / ship it in
