The past two times at fill up. I refuel the car get back in. The car won't start. It acts as if its flooded. The starter turns over but no fire. After 3 minutes it will start. When it does start it won't allow any gas pedal action or it stalls. After rough idling for a minute or so its ready to go. Then it starts fine everytime afterwards. Only happens at fuel up. SUP help please.
