As others have noted, I would check the wiring carefully for shorts or open circuit. I would also check the roboRIO power light and DS power tab for 5V faults (they may also show up in the DS log, I'm not sure). It may be that metal debris in one of the connectors or inside the roboRIO case or a short on a different sensor is taking down your whole 5V rail which would cause the described symptoms.
