Default KU engine stalls slowing down when cold

Folks,

Advice please...…..

My C3 Avant is used about once a month on average. It starts and idles fine.
I noticed the brake warning light comes on as I ease her out of the garage and goes off after a few minutes . Classic sign of a weak brake pressure reservoir. Brake pedal seems a little firmer than I remember, but brakes work well.
When I drive off all is fine but she has stalled on me as I slow down/halt.
Once the engine is warmed up this doesn't happen. I have cleaned the Idle Stabilization Valve with carb cleaner. I don't believe there are any vacuum leaks.

My question is: can a weak brake pressure reservoir cause the stalling?
