My Peugeot speedfight 2 wont start?

I was riding back from my local shop and i pulled on to my road and my engine died, so i tried to kick it over and nothing was happening its got over half a tank or fuel and 2 stroke oil. Some i pushed it back to my house tried it again and nothing. So i pushed it back in my garden and left it for a day tried it again and still nothing. So ive brought a new spark plug and a fuel tank filter pump and i kicked it over again and after a while its starts but cuts straight out and i don't know what else todo.
