Default Need Help on problem with Tekin 21.5 and Epic Duo 2 21.5

I am having issues with my Tekin 21.5 motor and my Epic Duo 2 21.5 motor:


TEKIN
I have a Tekin Redline 21.5 motor that I have ran now for 3 race dates, and this past race date (yesterday) it failed.

It started to make what I would describe as a "whirring" sound, sort of like something is off balance in the motor, not spinning true. The motor would then slow down to a crawl and stop completely.

This motor till now has worked great, never gotten hot (120 degrees max) and has great RPM.


EPIC
The motor will only start up when in the vehicle the car is given a push start. as soon as it comes to a complete stop, the motor will not start. I have tried other motors with the same speed control and sensor wire, and they work fine. I have also tried the motor in question on another working speed control and working sensor wire and it works fine there too.


Thanks for any help.
