We have a Kia Sorento 2003. While you are driving it hesitate rpm goes down and eventually it die. You start it again t drives for 2 or 3 minutes and it does exactly the same thing. We have changes the canister, valve, mas air flow sensor, Throttle Position Sensor, clean tank and checked fuel filter. The problem continues. We have put the scanner about three times and it shows no problems. This is a random misfiring and hesitation. Please Help. We do not know what to do anymore.

I read your problem on carpros. Com and am having the same problem. I found out through my dealer, that the problem is the vapor canister had fuel in it and had parts dissolve and backwash into my fuel tank causing the fuel pump to become clogged causing it to lose acceleration, when the car shut down the parts would come loose from the pump and I was able to drive for a little while until it happened again. Im having my vapor canister and fuel pump replaced and the tank and lines flushed. I should have my car ready by monday, hopefully this is the problem. I did see the broken parts in the filter and fuel tank, maybe this is the same problem you are experiencing.
