Sudden Beta Issue into stall

[BAL1515]

Hi All, in my last two flights in the 2024 Caravan Supercargo I was flying at 4000 ft and all was stable at cruise power levels. Suddenly the beta light pops on (an option I chose) and I quickly loose power. I had not touched any controls. I try to reset the power by pulling back on the throttle and then quickly full power, with no effect. Beta continues and I stall into the ground. Could this be a binding issue? Yet I thought beta was not possible in flight.

[edit : I have previously completed a number of successful flights before this phenomenon began to occur)

Any thoughts?

Thanks

I found the problem - it was a chaseplane issue / BTW Nick Loving the aircraft, great job!!!
