Fuel pump query

I'm having an ongoing problem with engine stalling when slowing down and/or braking. Not a consistent problem. Engine idle is about 1000. If I drive in 3rd, and don't stop or accelerate abruptly, engine will usually return to idle with no undershoot. But, if A/C is on and even if deceleration is relatively smooth, the engine drops below idle, sometimes down to 200 and then MAY return to idle or stall out. Is the fuel pump a likely problem? Many other things have been checked such as AIC, Jetronixs control unit, throttle position switch, ignition switch, relays, etc. but none seem to solve or minimize the problem. Does the fuel pump run continually or does it run in short bursts?
