We had this same problem today when trying to go over the bridge. We reproduced it by dropping the front the robot an inch or 2 against the floor. We then focused in on the cRIO. We shook it (a bit violently) and the 'Communication' and 'Robot Code' both went red on the driver's station.

We tightened down the cRIO, pulled out the modules, vacuumed it out, reseated them and tightened down the Digital ribbon cable. After doing all these it never happened again. If we had more time we would have tried one thing at a time since it would have been nice to know which it really was, but you know how it goes at crunch time a day or 2 before bagging it.
