Ok so after flying my Tarot 680 Pro hex for a while on a kk2 board while I was learning the Pixhawk on my quad. I decided I was ready to switch the Pixhawk over to the Hex. After everything was setup I went and flew it off the stock PIDS. It flew and behaved as it should have. Now after a recharge, I set up auto tune. The auto tune was running fine for just over 4 minutes when all motors just quit and she fell straight down from about 15 feet. Not too much damage occured. Bent motor mount, broken battery tray mount. The battery took the tray with it right off the frame (16,000mAh 4S) and unplugged it’self, I think… Upon checking all solder joints, power connections, I came up empty handed. Now I really can’t see the EC5 battery connector coming loose. It’s a snug fit. But I’m out of ideas. I’m using the 3DR power modual that comes with the Pixhawk. I also only powered the receiver off the output side of the PX4. All ESC’s are OPTO’s. Anywho, if any other info is needed ask and I’ll post it. I came up with this from the datalog file. Looks like a total loss of power.

I didn't find the right solution from the internet.
