Very strange indeed. Assuming that you've done all of the basic checks such as ensuring that the battery you are using is a reputable brand, the battery terminals are making good contact with the battery etc, then i'd hazard a guess that you are inadvertently pushing the middle button inbetween games (putting the marker into the OFF? state) only to have it switch off when you first pull the trigger at the start of the next game.
Next time you play, visually check the display prior to the break out and see what it states. If it does say OFF? then you know where the problem lies!
