I experience this. In my case, it seems to involve some mysterious
combination of the element cache, clocking, and logging. The lockups are
disruptive enough that I have to set org-element-use-cache to nil ---
otherwise I experience 2 to 3 lockups per hour. The problem completely
disappears with the cache off.

Alas, the baroque complexity of my .emacs and the size of my org files
make it difficult to discover the precise cause.

I'll see if I can provide an ECM.
