Hello everyone!

I will attempt to keep this short, I'm truly thankful for anyone who might have an idea on how I can proceed.

Setup:

FSX Acceleration

Honeycomb Yoke; Saitek/Logitech flight panels (Multi, Radio, Switch) using the original NEXT drivers; CH Pro Pedals and x2 Throttle quadrants - all connected via a 3.0 Powered USB Hub to a laptop

FSUIPC - all controls are assigned through FSUIPC and assignments removed from FSX controls menu

Carenado 690B v1.2

Known issue: Engine 1 and/or 2 failures (never simultaneously), mainly on the ground but also in the air. (mainly on the ground because that's where I stay)

Supporting Data: The FSUIPC Log shows the follow every time this occurs (example for ENG2): 

*** EVENT: Cntrl= 65992 (0x000101c8), Param= 1 (0x00000001) MIXTURE2_LEAN

*** EVENT: Cntrl= 65988 (0x000101c4), Param= 1 (0x00000001) MIXTURE2_RICH

Hypothesis: When the above happens the engine fails, I believe I have also seen the Condition lever "bump" in the Virtual Cockpit View to Emergency Cut Off then back and bounce back to where it was.... at this point I can restart the engine BUT the length of time before it happens again is seconds to minutes.  I believe preventing the mixture change to "LEAN" this the key to stopping this issue.

Attempted changes (none with positive results) :

Full reinstall; Bill's v5 Mod (do I also need v1-v4 or is everything included in v5?); unassigned mixture 1 and 2 to throttle quadrants;  disabled/enabled axes filtering in FSUIPC... there are so many variables

I have also run FSX without any external controls plugged in (flown with only a keyboard) and there were no issues.  I also had a flight without any failures using all the controls.... I'm dumbfounded what to try next.

added question about Bill's v5 mod needing previous versions also or if it is a standalone update.

UPDATE1:

After posting, I reinstalled a clean v1.2 from Carenado, then applied Bill's v5 and started the sim using the LITE version of the 690B.  I did not have any shutdowns (a very short flight without a landing).  I cut the flight short trying to understand the missing GPS.  Why GPS is missing... what am I doing wrong?  In editing the aircraft.cfg and bypassing Bill's -10 panel (ie using the original panel) the 530 GPS is right there in the VC as well as using shift+1.  I can see in Bill's -10 panel.cfg there are windows for the GTN750, but I do not have the 750.

I made edits to the -10 panel.cfg.  Am I missing how to use the 750 all together?  That would be interesting.

FIXED - I edited out the GTN750 from the panel and placed the 530 back in

UPDATE 2:

Still have the same original issue.  The engines simply will not stay running.

I'm still unsure of what causes this issue.  The work around I did find that is helping is to open smartCARS last, after lnm and AS16.
