Hi Don-P1126,
Thanks for relating your successes and techniques.  I use 2 Saitek Aviator joysticks, each programmed to different functions.  I recalibrated both of them but that didn't help, I still get the random shutdowns of 1 or more engines.  I hadn't thought about FSUIPC being involved.  Using an earlier version of it I never had the shutdown problem with the C-130, now with a newer version I do have the problem, I'll look into that.  And no, the condition levers have never moved, so that's not the solution.
