I'm with Henry on this one. Sounds like you are too far advanced. That would cause the heat and the heat would casue the power loss. If you absolutely can't use a gun on it for whatever reason, retard it some and try again. Like the others say, don't give up. I know it gets frustrating sometimes, especially when you're younger and have less experience, but that's how you learn and gain experience. Keep goin' dude, you'll get it. Let us know what's up.
