Make sure your fan is on and working. To verify, unplug the Rx8 from the receiver, power up the esc, the fan should run continuously.
Make sure the unit is updated to 249 software.
All those things check out fine. If it helps.. The power doesn't cut out when I'm driving it, it will happen after I'm driving hard and hit the brakes and then the ESC will shit off and restart on it's own. Almost seems like the volts drops so low in the battery that it will just shut down the ESC... But when I check the battery immediately after this happens, the batteries are around 3.9v per cell still.. So I don't see how it can be the battery.
Also like I said, it will run just fine for about 4-5 min until it starts doing this constantly every 20-30 seconds or so, it will just shut down and restart. Doesn't feel like the power is lower from a low battery either. It still runs fast and hard between shut downs.
