Try slowly ramping up the power to the motor instead of setting it to 100% instantly. The Jaguars have internal overcurrent protection which tends to trip at abrupt changes in power, especially with large loads. A good indicator of this happening is a yellow light on the jaguar blinking for 3 seconds when this happens. The length of time it blinks will always be constant in an overcurrent fault.

Jaguars will not brown out due to low voltage until 6 volts, you can test if this is the problem by looking at the voltage reading of the overall robot from the driver station. Using a battery with low charge will usually be the culprit in this situation, but I wouldn't expect a single 775 to drop the voltage of the entire robot enough to cause this problem unless the battery was already mostly discharged.
