Narrative: We landed around midnight after an 11 hour duty day and we were both tired. After exiting the runway I said my normal 'Flaps up; After Landing checklist; shutdown two;' yet turned off Engine Number 2 myself but never told my First Officer that I did. When the First Officer finished his After Landing checklist; he proceeded to shut down Engine Number 2. Unfortunately; he shutdown Engine Number 1. By shutting one engine down myself I kind of set him up and so we found ourselves with no engines on the taxiway. I immediately started the APU and made an announcement to the passengers and ATC. After the APU came online we started one engine and taxied to the gate. We had a long day and were both tired. I even commented on this during the descent to be extra vigilant. I should have let the First Officer do his job like I asked him and not shut down one engine myself. I am aware of what the AOM says in regards to who should shutdown engines during the taxi-in; yet being tired; rushing to get things done got the better of me. And the First Officer should have looked what start lever he reached for. I assume he was in mindset as I. Needless to say we all learned a big lesson from this.


Second narrative: After landing; we cleared the runway and taxied to the gate. The Captain asked for the After Landing checklist and [to] shut down Number 2 engine. The First Officer did the checklist and [prepared] to shut down the Number 2 engine. What happened was the Captain shutdown the Number 2 engine and the First Officer shutdown the Number 1 engine accidently. It was like it happened simultaneously (quick 1; 2.) After that happened we brought the aircraft to a stop and set the parking brake. The Captain informed the passengers and flight attendants what was going on. We started the APU did the checklist and restarted the Number 1 engine and [continued the] taxi to the gate. Some things I think would have helped don't be so quick to shutdown that engine; meaning physically moving hand to engine start lever to cutoff. The Captain should not have shut down the engine after landing and taxi the aircraft. If I remember correctly it was dark near the engine cutoff levers; I think there should be more lighting near the engine cutoff levers. Slow down and physically verify before flipping or moving switches. I think another factor was the long duty day with a long sit.


Synopsis: During a late night taxi to the gate after landing; the Captain elected to shutdown the Number 2 engine while the First Officer was performing the After Landing checklist. When the First Officer reached to shut down the Number 2 engine; he mistakenly shutdown the Number 1 engine. The crew recovered by stopping the taxi; starting the APU and restarting the Number 1 engine; followed by a successful taxi to the gate.
