CAN Talons Randomly Stop Working?

[CPotvin]

Yesterday, and today we have been attempting to troubleshoot a problem with the CAN Talon SRXs. Basically, what is happening is we are able to enable and drive our robot for somewhat random periods of time before the Talons stop working. When the talons stop working they show that they are receiving a neutral signal, and we have no control over them, although we can still control our intake system which is using PWM Sparks. Also, last night when we were troubleshooting the robot would have 3 motor controllers go neutral, while one would go forward til the motor it controlled overheated, and turned off, so we switched that Talon and now they all go neutral. The timing seems to be consistent in the form of they malfunction at intervals of a minute (ie. 1 minute, 5 minutes, 6 minutes).

If anyone can let us know how to fix this, and whether it is a programming or electronics problem that would be greatly appreciated.
