My Saab 900 SE Turbo did that when it had a clogged cat, it would stall out if I stopped after operating temp, Power would drop under hard acceleration and it would stink life sulfur or rotten eggs on hill or if the motor was under load for over 15 seconds. Also check to see if you cat glows after a good hard drive... The check engine light won't come on in an OBD0 or OBD1 car if the Cat is bad...
