Thank you very much for the suggestion - I will give it a go and report back.
Just tried and it worked. Solved my problem. My old CHProducts joystick has had a lot of work over the last ten years, and even replace two potentiometers in 2011. May be time to consider a new one. Or more pots
Thanks again

This is an issue across the board with ALL add ons. Not just the TBM. However, Saso, who coded the TBM, has recently created a plugin to stop it from happening.
Please read all documentation that comes with it.
the aircraft is entering CWS P mode (pitch) as seen on the FMA. This is a good indication your yoke/joystick is sending noise on the pitch potentiometer overriding any A/P PITCH mode.
please go to ixeg 737 menu preferences and move the nulllzone slider all the way to the right, this should cure the problem.
Hope this helps
