you know it happened once to me..... i met anakin who used to drive a 323 like mine. he did say his car also sometime kena like that. after the engine die, can it crank? or if you try to start nothing happens and you wait few minutes then okay? if that's what happens, there is a controller (i think it's the TCI or something) stuck to your firewall behind the fuse box in the engine bay, it's covered with a soft rubber cover. whenever things like above happens, i just unplug and replug the controller connection. apperently, the connection is loose. but i wonder why it only happens after the engine is running slightly hot esp after stuck in a traffic jam?
