My Beechcraft BE23-24.
Had a brief engine failure on return trip. Super slow leak from left tank sump, that wasn't seen parked in the grass (would puddle on pavement). When we got to altitude, the vacuum from airflow sucked the tank dry quick. Had full engine failure for nearly a minute. Engine died, pitched for best glide, located emergency landing spot, ran through emergency flows which got it restarted, and diverted to nearest airfield. Left tank bone dry. Working the sump got it sealed again, and after refueling and monitoring the sump for 30, and calming my nerves for 30 we got back on our way, but late enough to get stuck in Sterling for 4 hours waiting out the afternoon thunderstorms.
The saying "When the engine stops, your heart stops" is quite true. Thankfully I'd drilled this scenario hundreds of times, so even under the crazy stress and HUGE adrenaline rush, the training took over and solved the problem before it got any worse.
