Fourth qtr. 12.00 mins. to play team gets a first dwn.
My question is "Does the clock stop to move the chains and if so when whole game,last 2 mins. etc."

Under High School rules (those 48 states that use NFHS rules), the clock stops the move the chains for the entire game. If this is the only reason the clock was stopped, the clock then starts on the ready-for-play.
