I joined a server and had all my items from the day before including clothing, food, weapons, ammo, etc. I played for a while, laid down safely (not bleeding, being attacked, etc.) and exited. I joined a less populated server and it turned out to be night. I was quickly kicked by the server admin and rejoined another server to find it to be day time but all of my items were gone and I respawned. In essence, I died.
There was no warning sign to my imminent death!
