Honestly, it's become a monthly occurrence for me too. Lost a $15k retainer last quarter out of nowhere - client said they were "reassessing marketing spend" but I found out later they'd hired their niece to run ads. you can't control that stuff. Best you can do is run your own diagnostics, learn what you can, and keep the pipeline full. a strong pipeline is the only thing that's stopped me from having a full-on panic every time one drops off.
