A couple of days ago I drove into a parking garage (concrete structure) and the GPS lost reception. I turned it off after a few minutes. When I returned to the car I turned on the GPS (Tom Tom 1 3rd ed.) and then drove out onto the street. The GPS could not get a satellite lock for about 20 minutes - it usually locks on in less than a minute. What caused this? Did it reset as a result of the lost reception in the garage? Is there a way to avoid this situation or speed up the recovery?

Just guessing, mind you, based on some other reports and experinces but you can try two things:
1) Turn it OFF before it loses reception and don't turn in back ON again until you are out in the open.
2) Drive out of the garage, STOP and the turn it back on.
Recovering from a complete signal loss or being off for a long time often takes a LOT longer if you are moving.......and longer still if the mounting location in the car makes signal strength marginal.
If you were driving/moving while it was trying to lock it can take a LONG time.
My GPS will ask me if I've moved a significant distance while off. I think it's about 100 miles. When I don't respond, it can take 5 min. or so.
I was driving/moving so that was part of the problem. Next time I will turn it off before going into a GPS black hole. Thanks for ther help.
I had a few times that my TomTom One 3rd would not lock on after a period of time. I just turned it off then back on and it locked on normally.
The only thing I would add is, once out in the open stay stationary until Ephemeris and Clock Data are regained and then wait for satellite lock, then your accuracy will be more spot on!.
