Yep, I was powering the Arduino with the BEC. I am now powering the Arduino with a 9V battery and everything is functioning properly.

The ESC should have an optional voltage cut off which you need to turn "off". Since the rules state that the Arduino controlling the motor must be powered by the main battery supply, attach separate leads to the battery and run them through a voltage regulator and then to the Arduino. My vehicle from nationals used this kind of work-around and it fixed the Arduino-resetting problem. My vehicle is posted on the best of nationals page if you need a visual

Thanks for the reply. I found the rules clarifications on the Soinc website and see that it says that a battery may be used to power the motor, and another battery may be used to power an Arduino. Here is the link for this clarification: https://www.soinc.org/node/1767

Does this mean that I can power my Arduino from a separate power source (9V battery), and power the motor with a different power source?

Thanks!

It seems like that would be legal, yes. I was not aware of this clarification before nationals so I had to do it the harder way, but either way, it should not effect your vehicles performance.

Ok, that's great. Thanks for the help!
