my Peugeot speedfight 2 just died on me?

my Peugeot speedfight 2 just died on me, the fuel guage is saying low but i can still see the fuel in the tank, there is also 2 stroke oil in the oil tank too so cant see what the problem is unless even though i can see some fuel in the tank it needs topping up more before it will turn over. when it died it started up a couple more time then completly died and now it wont turn over what so ever help!
