From what I've seen 10 minutes on a trex is too long a flight. You probably have run your lipos down too far and they have given up the ghost. classic sign of tiring lipos is power loss a lot sooner than you're used to.

tired lipos will also charge ok and show proper voltage when charged, but can not deliver enough amperage to fly properly due to high internal resistance.
