Re: Fuse in cRIO is blown.
I would definitely look into the shaking causing a transient short.
The cRIO is chassis grounded so if it contacts the metal of your frame during violent movements (and you already have one existing connection to your chassis) the situation you described would be the likely result.
I would check ALL your connections and make sure you don't have a connection between any electrical systems and the robot chassis. This means taking a multimeter and verifying that resistance is greater than 10M ohms between the robot chassis and the following:
1) Battery negative (probably easiest to hook to at the PDB)
2) Battery positive (probably easiest to hook to at the PDB)
3) Each motor lead (you have to test each one on the motor side of the Spike/Jag/Victor)
The last one is the one that doesn't get tested very often, but can cause the exact same problems as the other two.
