Strange problem with old ST.51 - 
Had a strange problem with an old ST.51 today. It's ten years old so is a pre-China version. It would start, run and idle just fine, but after 3 to 5 minutes of running it would suddenly die at wide open throttle. Tried three new plugs, checked the tank and made sure it was not foaming, tried a larger prop (12-6 instead of 11-6 APC), and changed fuel. It got some better, but nothing solved the problem. Resulted in five dead-stick landings. It has been on the shelf for eight years, but it has about 50 flights on it and was never a problem in the old days. In fact, I got mine after a friend ran one on a Sig Four-Star 40 all season without a single problem (200+ flights). I am really in the dark over what to try next. Any ideas would be appreciated.
