Well, if the problem persists with different ESCs, then it has to be elsewhere. Some things I can think of:

1) The battery could just be weak, or maybe one cell is weak

2) The battery connector is dirty, worn (from hook-up spark, or just from use)

3) Motor is faulty. But again, this would usually be evident by the motor, ESC, and/or battery getting hot from the large current draws.

I would not suspect motor wiring because if the motor wires or connectors had a higher resistance connection, you'd probably have abnormal operation, which is pretty obvious. But anything is possible.

An eagletree device would probably help here. It won't tell you if the motor is bad per se, but it would show you the current and voltage points and can help you narrow the search.
