The problem typically does not reveal itself in the pit, since the drive motors aren't under the same load as when they are pushing bots on the field. At least one bot with this problem would stop and restart during the match and appeared to be running without operator control.
This seems a little silly to me. 4 amps is the Maximum that the VEX controller can supply to the motors. I highly doubt that this means that if you draw 4 amps that the controller will shut down. The Controller itself most likely runs off it's own "line" of power. i.e. those 4 amps are for the motors not the controller.
