Exactly. Sounds like you are venting your stock BOV to the atmsophere hence it wants to stall everytime.

Stock bov (recirc valve) do leak.  
If you want to run an open to atmosphere setup switch to an aftermarket one.  
If you want to keep the stock bov/recirc valve, then recirculate it back into the intake.
