    I have same problem, i thought it was the timing belt but after the replacement it did the same thing. The belt was bad but not sure WTF else to do.

    I had this exact same issue last week. In my case not only was the timing belt snapped, but it grenaded the No. 1 cylinder as well and KIA is not wanting to cover it because I did not change the timing belt at 60K mi. The car has 71K on it.

    I had the same thing happen in September of 2007, I had to have the timing belt and Crank Sensor replaced at dealer, then it just happened again (January 09). Dealer says parts were only good for 12 months, so I am out of luck and now need to pay another $480! So, according to the dealer and customer service at Kia, we basically could have to put that much into it every 13 months for a part that should only have to be replaced every 60,000 miles! I WILL NEVER BUY A KIA AGAIN!

Check the crank position sensor.

Also make sure the belt tensioner is in good shape(its hydraulic) Also there is a circular metal plate behind crank sensor that needs to be clean and not cracked/dammaged. check these items and let me know if it fixes.

The timing also has to be perfect or you will have issues. there are timing marks on the belt pulleys

2004 kia optima stalled while driving down the road after 15min or so it willstart backup

if check engine light comes on, get it scanned. you can get it scanned at auto-zone for free. as long as the check engine light is on. but it sounds like a bad crank sensor! that is the way the sensor is. it will die out and about 15 or 20 minutes it will restart. get it scanned. good-day! it controls the timing of engine.

Change your crankshaft sensor located behind lower timing belt cover. The way I check it is to unplug the maf and see if it will start if so stop the engine and do a diagnostic 3 DTC's should come up on screen ,one would be the crankshaft sensor. This should be done by a experienced tech.

Car will start but dies after about 10 minutes. Will restart after about 5 minutes but dies again after running a minute. Replaced fuel pump, fuel filter, attempted to clear codes by disconnecting battery,...

Check and see if you have spark when it won't start. If it don't check the ignition module, Coil Packs,Crank and Cam Sensors. See if that gets in the right direction and let me know if not get back we will see if there is some more things we can look at. Ok thanks Bear001

This could be multiple issues.
1.) timing belt
2.) Crank sensor
3.) Fuel pump (although usually they do not just die they get weak)

Check these let me know.
