Check your fuel filter. It may be clogged. If it is, you'll have no problem with starting and idling, since these require relatively little fuel flow, and even a clogged filter can usually flow enough for that. When you try and accelerate, the engine demands much more fuel, and a clogged filter may not be able to flow enough, which can shut the car down.

The fuel filter is located in the fuel tank, pump removal is required to replace. There is an inspection cover behind the front seats on the floor to gain access to the pump. stupid idea. but whats not stupid about kia.

coil or injectors getting cracked or dirty and needs to be cleaned.
