•Take off heat protection to see if that is the cause.
•I normally only run my Lipos down to around 60%, so check the amp current your motor is pulling. This is adjusted by endbell timing. If your endbell timing is too high, it will cause more motor heat which will cause fade over a run and also pull more amps draining the battery quicker. Both factors will result in less power. I would try turning down the timing and putting a fan on the motor. My money is on the motor and NOT the esc.
