Motor Stops - Motor Overheating

Hexacopter
Motor - A2212
Prop - CF 8"
ESC 40A

Can anyone shed some light on the problems I’m having here?
Randomly a prop (same one) stops and I have a motor overheating. Check video below

I had a similar issue, and de-soldered and re-soldered the ESC and motor leads. That cured the problem.
