You will need to drive some more to see if the problem is corrected. Your stalling condition may also be caused by a dirty throttle body causing a low idle condition. If the check engine light comes on again have the codes check out. The catalytic converter may fail, setting a code p0420, this fault should be repaired but should not cause your stalling condition.
