Make sure the the gasoline is clear and clean and has a good octane. Use two STP octane booster bottles (the orange bottle) for a full tank, if your problem solved then it's a gasoline problem, if not you need to check the spark plugs and the spark cables as well. Use only Bosch spark plugs and Beru spark cables (NOT BOSCH SPARK CABLES). All the best.
