Not sure what causes it. I just bought a 2002 Galant, and mine seems to have a similar problem. The only difference, mine sometimes dies when idling. The engine runs fine while driving. Only when idle. I'm hoping that I can resolve it by idling it up a bit.

try looking for any leaks in your intake tube and throttle body. Maybe the plastic cracked or the clamps arent tight, causing you to lose air. The engine is adding fuel for air that is not there anymore, causing you to stall. Also try cleaning your throttle body
