Then you are having a stalling problem. but why? do you lose spark or fuel? The vehicle is not supposed to stall. runability issues reduces engine vacuum, right? and this has a vaccum suspended booster, yes? Are there codes stored? is the vehicle behind on maintenance? a safety inspection and list of obvious needs may help.
