Check for bad spark plug wires.

Remove air filter housing and check the idle control valve hoses -- your idle control valve is sticking closed. The key symptom is stalling when coming to a stop only -- if it quits while running normally, it's the fuel pump relay or fuel pump(s).

If the idle control valves are rock hard, they are leaking. Check all the rubber vacuum line connectors, chances are they are bad too, and all your symptoms sound like a vacuum leak. Make sure the brake booster line is tight and the booster doesn't leak.

The rubber boot between the throttle body and the fuel distributor is probably bad, and check for leaks at the injectors with a bottle of carb spray -- while idling, spray a bit on each injector. If the idle changes, tis leaking air. Get new o-rings for the plastic sleeves the injectors fit in and change those, too. Best to do the injector seals, throttle body boot, and ICV lines all at once, as the injector lines have to come off anyway and the ICV line to the manifold is a real bear to change with the throttle body on.
