Sounds like a weak fuel pump. Check the fuel pressure and if its not within specs replace pump.

Your saying when you come to a stop,and want to take off and then it out no where goes as you try to acclerate.? Of course it neither one of them 2 things of concern first it sounds like you are low on transmission fluid.you need to check the transmission level if it is low and or doesnt register on the dipstick then what you have describe is the problem low on transmission fluid. Here is how it works when you have the appropriate level transfluid is sufficient to move the car.when your low its not enough fluid to engage the gears and when you step on the fuel pedal it forces to fluid to shift thcar and this is bad on engine and transmission, so check the level. Just for now make sure you have the appriopriate level
