The batteries are most likely going dead, they will run a while then stop. A new set of batteries should last 50 hours on the slowest flash mode then they will be dead. With a good set of batteries you may get longer than 50 hours, cheap ones less. To change the batteries remove the 2 screws then use a small flat head screw driver and push a little on each of the clear tabs. You have to go back and forth to get it to open. It will be hardest the first time, then get easier.
