Does pausing a campaign lose its history?
No. Pausing keeps everything. Deleting is what loses it.
The short answer
No. Pausing keeps everything. Deleting is what loses it.
Conversion history, learning and settings survive a pause, which is why pausing is almost always better than removing.
A long pause does mean the bidding effectively re-learns when you resume, so expect a volatile first fortnight back.
