Before you all rule out the sensor wire and I know you changed it etc...
2 things... Did you swap motors, the sensor board in the motor can be jacked which will cause the motor to run but in sensorless mode, or I have also found out some sensor wires do not seat all the way without a little coaxing on the esc. Went round and round with a couple of these esc's and both times it was the sensor wire was plugged in but not 100%. So I now take a ball end wrench and really seat the wire, and no issues since.
Good Luck, it may not be the end all fix but it may help.
