Sorry, I'm not familiar with the BASIC Stamp Micro-controller. However, you should be able to diagnose where your problem is quite easily. With your breadboard, jump the +V to to the base (B) of your transistor. Your LED controlled by the transistor should illuminate and stay illuminated. If this is so, your flashing problem is caused by the device that signals the transistor, (I'm guessing is your BASIC Stamp).
