Hyundai accent 1997, engine problem when fill gasoline.?

When I buy ​​gasoline the car begins to shake, as if failure to turn off the engine, then after a while he goes failure (like a new car). Soon the light "check engine " comes on, sometimes want to turn off the engine. the situation is intermittent, but at high speed no problem, only when in low speed, like when I go to accelerate. sometimes the problem is solved when clear the PCM.
