Putting back in the fridge killed you; you restarted with a cold peice of meat. Next time leave on and stay in bed. You didn't say what temp you were cooking at.
The stall is well known, read up on it - especially sites that have charts and graphs if you are a dork like me. It will totally make sense.
The stall even happens in my oven, tho not moisture related. If yall had not noticed i'm big into pizzas and with that the oven opens often. What I have done in my gas oven is add a layer of 9 bricks on the bottom as well as two 1/4" slab of steel baking sheets (not a fan of them but still useful). My oven stalls at 435 or so on the way to 550. Usually for about 45 min. Then once hits I still keep on for another 30 min before I start making my pies. When I open the door to do pizza things, the heat recover period is almost nil. So, not the same 'stall' but it explains it a bit - the extra thermal mass I've put in sucks heat until it gets to the core of my bricks, or meat if cooking.
