no, not likely. you need to check for spark, fuel delivery and compression. you all of these for the motor to run. take it to a shop for a diag and a bid.

have you check fuel pump relay?
You need to follow logical diagnostic procedures when the engine stops running to figure out what is going on. A proper wiring diagram, a good volt/ohm meter is the least you will need, an oscilloscope and scan tool may be needed to get to the root of the problem. Kia as a car manufacturer put a lot of great technical information and work shop manuals on line for free for Kia owners.
