I feel foolish, dismissing these suggestions, but it finally clicked. Loose skewer, flexy rear triangle, especially under load. Duh! Just came back from a ride and the angels sang once again.
It's not madam and you don't owe me anything. I've been there before. I've even switched out press in BB bearings when all I had to do was tighten that rear skewer. Lot's of force happening around that part of the bike.
Glad I could help, enjoy the quiet.
