try having it plugged in the wall and press and hold the power button and the volume down button at the same time for twenty seconds and there should be a red led lit to identify if the batt is charged or not if so then it might be bad hardware if it does not come back on in that case google team will be needed
hope this helps
Having your device up and running at all times is vital Timmaness, we'll be glad to help out. Have you made any changes or updates to your phone? Does the phone have any physical or water damage?
Timmaness, please attempt to put the device in Safe Mode as shown on the following web page https://www.verizonwireless.com/support/knowledge-base-220011/. Then does the device continue to power down?
