Eddie, a few years ago (before I began using the idle up), and most likely due to earlier versions of ECU software, most of my flame out happened when I went to idle and immediately added power again. (I do it in some maneuvers).
My theory is that when you suddenly cut the power, the UAT begins to expand (the negative pressure created by the pump suction ceases). When you apply power again while the UAT is still expanding, the pump: either starves, or the learned voltage is not enough to maintain the flow during that sudden condition. Again, this is just my theory. But it happened a few times in different installations and with different turbine brands.
In some opportunities I have also had turbine stagnation (doesn't want to accelerate).
All these disappeared after using idle up.

It may also have to do with the fact I fly at density altitudes of over 2000 ft., I don't know.

But anyway, I am not suggesting the use of idle up, but a heads up to those who use it.
