I had the same exact problem on my 2005 kia optima. This problem happened a year ago. The car stalled without any noise on the highway. I got the crankshaft sensor and the timing belt replaced. I got the new parts myself and got it installed by a mechanic. So far it has been working good.

Today on the freeway my wife's 2006 (early model) Kia Optima had a vibration, fluctuating RPM and then it stalled.When it stalled we saw al lights on the instrument panel light up. No check engine light stayed after staring it again.We drove for a few minutes and it died again.
I opened the hood on the safety lane and checked the battery poles and belts.I could not see anything out of the ordinary. But my wife said a day before a bird flew in front of the car's grille and she found the bird's skeleton at the driveway that evening.
We drove the car home without problem. 15 minutes or so. No check engine light.
What could be the problem?
I am using Mobil 1 Extended Performance oil for almost 8,000 miles now. With synthetic oil my usual oil change interval is 7-8,000 miles usually.

Probably too little too late for your car.
My 2002 Optima was shaking violently when at a stop in drive. It started about 66000. When I would go into the dealer for an oil change, I would mention it. He would give me answers like try a different gas. Next time he would say, "Oh, dont use Sams Club gas." Turns out he was trying to prolong it past my extended warranty of 75000, so he did not have to pay to fix the real problem which was all motor mounts were cracked. The shaking got progressively worse as each mount failed until a friend told me to change the mounts. By then, the damage was done. Violent shaking caused cracked refrigerant line, plus others. Cost $1800 total to fix.
Maybe this may help someone.
