Random Spark Advance Drop at Part Throttle
2005 Dodge Magnum with a 2010 5.7 Hemi:
When trying to maintain speed (30mph+) I am running into random spark advance drops (from 22 to as low as 1 or 2 degrees advance) with no other change in data. My accelerator position % flutters around and randomly drops as well but I have not yet seen a correlation between the two. Would anyone happen to have some suggestions or things to try?
Thank you.

Very strange...
What about transmission slip ? Maybe a correction from drive train.

Wow its been a while since you responded. I have moved on to thinking its trans as well. Maybe the power% request?

try to log all torque values, spar correction , fuel cut and throttle torque source.
