What he saidSounds like it might be bootlooping. If you bought the phone from Google contact their support. If you purchased it somewhere besides Google contact LG support directly. LG repaired my bootlooping 5X free of charge.
What he said
I have to get me one of thoseYou already bought the "I bought an LG phone and all I got was this stupid bootloop" t shirt didn't you?
Nexus 5x Stuck in "Google" logo page.
This exact thing happened to me on 7/25 as well. It booted once more, then back to bootloop. I managed to boot to recovery, cleared the cache, and it never booted again. Long story short, I called LG who informed me that I could send the phone back (on their supplied label) and as long as there wasn't any physical or water damage, they would replace it under warranty with a refurb (my phone is 18 months old). Call LG at 800.243.0000. Just give whatever response to get to a live agent--there's one set of responses that will give you instructions to go to lgmobilerepair.com--don't do this because you can't choose Nexus from the phone model menu. The live CSR will give you an return auth and email you a shipping label. One other thing is have your IMEI number handy--it's impossibly small on the inside of the SIM tray.
