Took car out for a bash as per. After 15 mins or so the engine cut out. Thought it was out of fuel but when i checked the tank the fuel pick up was still submerged in fuel. Tried to start a few time but no joy. Got home and checked all the standard stuff; air filter ok, fuel lines ok, got compression, spark plug ok but still wont start. After a few tries the engine started to feel stiff as its quite hard to pull the pull start. Anyone any ideas as im guessing it could be terminal? Hopefully will be covered under warranty.
