Shai,
There a few possible problems that you should check.
1. You may have a loose battery connection or poor crimp in the Anderson 50 amp connector. Are any of the battery connections getting warm after you practice? This includes any of the #6 AWG wiring.
2. The main breaker has a known manufacturing defect that allows it to open with vibration. To check, lightly tap the breaker red button. If the lights on the robot flicker, replace the main breaker.
3. Does the 5 volt LED turn on if the camera is not plugged in? Are you using this year's camera or last year's? There is an electrical difference. Last year's camera has the case tied to the negative lead of the battery. It must be insulated from the frame of the robot.
4. Is your Crio insulated from the frame of the robot?

If the Dlink is loosing power, it takes 55 seconds to reboot. Is this the length of time you have no communications? When you think you have a low battery, what is the voltage reported on the driver's station display?
