Motors stopped working on air and crash (Log file attached)

Hi guys, this is my first post here.

I build a quadcopter using the following:

Yesterday i successfully tune PIDs without any issues. Flight was very steady and smooth without any oscillations.

Today i just flight a few minutes and i notice small oscillations and suddenly my quadcopter motors stopped working on air. I suspect that might be an ESC failureā€¦

Here are my log file
Any help will be really appreciated.
