If it is windy outside, you may be getting just enough of a breeze to blow out the pilot light -even though the covers are shut. My heater is in the garage, and even w/ the garage door shut and the covers on the heater shut, very windy weather can still cause enough of a draft to blow out the pilot. You could try to find something to block drafts around the heater such as a hot water heater blanket.
When the engine is turned off, the car heater can still work by using the remaining heat stored in the engine and circulating it through the car's heating system. This allows the heater to continue providing warmth inside the car even when the engine is not running.

Here are some simple steps you can take to see if your garage door motor is still working. First, check to see if the transmitter on the wall inside your garage still opens your garage door when pressed. Second, check your photo eye to make sure it's not out of alignment. Thirdly, if your garage door track is out of alignment, it can be a serious issue.
Yes it will, engine coolant still flows through it when engine is running.
Could have a clogged line feeding the heater core. Disconnect return hoses from the heater core and verify coolant is flowing through the core.
Never Shout Never still exists.
Yes, as long as you connect the incoming and outgoing heater hoses that were connected to the heater core together. You will not have a functioning heater or defroster but otherwise it will be fine to drive.
