Make sure the pressure hose to the muffler and the hose for filling her up was not swapped. I was having a problem like you where it would die after throttling up..I discovered the hose for filling up the tank was connected to the muffler. The 3 line fueling system is nice but not if you forget to re-connect them right. ONce I swapped them around the problem went away.

I have to stress to you both. The simulator cannot simulate real life events like depth perception. That was my problem. I thought the plane was much closer to me than it actually was. Thanks for your simpathy. I am not giving up though.
