Sharpsman--My Lyman Mag 20 did the same thing after 3 years. I repaired it, and it lasted another 2 months, then quit again. Its been sitting in a corner of my shop for about 6 weeks, and I doubt if I will fix it a second time. I'm using a turkey cooker and a cast iron pot. It may run out of gas, but it ain't gonna short out. Shoot straight, rdnck.
