Manta B starts but WHEN I DRIVER out again

hey people in my last post I have described that my manta b Gte always runs out after the start… have now cleaned the fuel lines tank filter and pump… the ignition set again and jetz remains the manta already…. I can give in stand on gas, he also takes up that well over all speeds, … so quickly make a test drive!—> because also the new problem The manta drives easily only when it rolls and you do a little more he wants to give gas starts to jerk, turns at most up to 3000 u/min and if you then go off the gas for a short time, the manta goes on again… after waiting for a few minutes he starts again without any problems and then the same game from the front.. someone ne idde as I can eliminate it?
