The flame uses up oxygen as it burns and when enough has been used up the flame goes out.
The flame produces a gas (carbon dioxide) which won’t burn and when enough has been produced, it puts the flame out.

Answer:
Burning of a candle needs continuous supply of oxygen present in the air. By covering the candle with a jar,the supply of oxygen gets cut and as there is only limited quantity of oxygen left the candle burns for a moment then goes off completely. Since there is no oxygen left in the jar.
