While I would go as far as saying memory leaks are rare in Labview, I would follow marks advice, in the console look for a watchdog error. It would sound to me like your watch dog isnt gettting fed, he flashes an error on the driverstation and the driver is so busy watching the robot that they miss it. If that is the case, I would disable the watchdog and see if that fixes it
