"ESC's have their own power supply. - they often beep on PWM loss. PWM goes away when pixhawk loses power. - so they beep.  (Pixhawks PWM microcontroller shuts down too) Redundancy; Pixhawk is able to take up to three different power…"

Andre K. replied to Staq Koenig's discussion All motors stop suddenly with Pixhawk
"no, if all ESC's was out of power/underperforming for any reason, you'd see logs indicate a huge increase in motor PWM and ThrOut. What you see is attitude get out of control, and the three other motors dropping throttle in order not to…"

"oops, my bad -(posted some ansers to wrong threads.) - in your case log ends suddenly at ~19200  -  most likely a los of power to pixhawk, check it's power (+5v) and add some redundancy."
