Sounds like an overdrive solenoid sticking in the transmission. Might have the transmission flushed, with a positive displacement unit, using BG transmission cleaner and additive. If the solenoid is sticking, then it won't unlock the torque convertor, stalling the engine when you slow down. GM was real bad about that as well. If it was dirty throttle body, I would think that it would happen more often than not.
