my theory and i don't know for sure.(it is only a guess)

when you are coming to a stop, or maybe slowing while going down hill, the fuel in the float bowl surges forward starving the internal well of the carb which could possibly be starving the idle circuit.

you can try opening the mixture adjustment before slowing down.

i had a sedan that did the same thing, i spent lots of time with jets and float level and could not rectify the problem. if i was driving in the city with lots of stop and go i just ran the mixture rod open a bit more. it wouldn't stall when doing that.

on the hyway i could run that mixture rod almost closed.

it may help to set the idle a tad faster.

its one of those things that can take a while to figure out, or you just find a work around.
