Yes it sounds like the Idle Air Control Valve is not working.
The air escaping sound your hearing when the engine dies is most likely air trying to get past the closed throttle plate. That is happening because the IACV is not allowing air past the throttle plate at throttle plate closed position.

But I am just guessing.

You say it runs smooth at around 800-1000 RPM... A vacuum leak big enough to stall the engine at idle would most likely cause rough running at 800-1000 RPM and get smoother the higher the RPM went.

IACV is pretty simple you can do a search here on the forum and find info on cleaning them.
So I would start with the IACV
Lets us know how you go
