OK, I've flown this leg four times now, everytimes it ends with nose-down and crash. The leg was EEKA-ULOO and I was flying with real weather from Xplane.
This was my first recording inside Xplane and I didn't notice resolution was so bad 640*

This is weather from littlenavmap (pic1):
As I started my descent from 18000ft I turned on de-ice (the settings can be seen on video at start 00:05 , prop max, engine on, auto-cycle cont, pitot heat).
-Steady descent 1000fpm towars 3000ft IAF PS009 I think)
-flying into cloud at 01:10 things start wobbling, AP can handle no biggie. Wind is steady 19 knt from from 5 o'clock
-01:20 see speed jumps around and soon I decide to increase power
-01:45 pretty much stablized again, 01:51 as you can see weather was a mess.
-02:50 speed start to drop. Wind didn't change (at least on EADI).
After that I have no idea what happened, but it happened 4 times on a row. As seen no trim issue (this was discussed recently), trim is at 1 or so.
-03:10 here we go, AP can't handle it anymore. Switching to manual flight, full throttle. VS is 3500fpm.
I was about to turn to approach for RW19 and wind was from 200.
Any comments welcome.
