Start power helps higher pole count motors get started. Now, with the new firmware that cc came out with recently, this setting does not really need to be changed.

You are most likely hitting the lvc at full throttle. What do you have it set for? 12v? You can set it much lower for testing purposes, but only on a fully charged pack, and do not go full throttle more than a few times. Sounds like under load the battery voltage is sagging low enough to trip the lvc, causing the power loss you noted. If it still happens after you disable the lvc, then I would say to reprogram the MMM to your radio. You may need to reset all of the values in the radio to zero/centered, and then reprogram the mm to the radio. You may be going full throttle and the mmm is not seeing the full travel of the radio, and going into failsafe mode.
