That would've been my exact suggestion.
Are you sure it isn't external? There are a number of heat shields on the exhaust system that can break a weld and rattle including especially the one above the catalytic converter.
Stalling? Could be many things, plugged catalytic converter, maybe bad crank position sensor? I'll leave the car mechanics to help you diagnose that one?
