I recently had this car tuned up, new fuel filter etc. It had been sitting for many years without being driven. When I approach 50 mph it loses power and almost dies, sometimes it does die. Also when I accelerate from a complete stop it hesitates, then kicks in. Do you know what this could be?

Thanks
