Check engine light code indicates all cylinders misfired, car can run for approximately 15 minutes or 10 miles before the car shudders and the cylinders stop firing causing the rpm's to go to zero and the car to eventually stall. Thought it was the coil pack which I just replaced but it did not correct the problem. The head gasket appears not to be the problem, it seems to be heat related since it hits a certain time or mileage every time it happens especially if It gets stuck at red lights where the vehicle is not getting air flow. Any suggestions or recommendations?

Did you ever get this fixed? If so, what was the problem, I have a 2000 Hyundai Sonata, 2.5L V6 and I have the exact same problem. But, I also I found that when I rev'd my engine it wouldn't go past 5000rpm and it would just sit stay at 5000 until I let out on the gas then the gear would switch and same thing would happen. There is a recall on Mass Airflow sensor on this year but mine was changed in 2003, I have a feeling its the pxygen sensor again, but can you confirm?

Thanks in advanced

Yes I did get the problem fixed. It was several issues. Two sensors (torque converter sensor & cam shaft sensor) were failing and my transmission was going bad, they replaced the transmission under warranty since I am the original owner. After they fixed it my oxygen sensors went out as well. But the original problem is fixed. I am not sure what caused what but I think the two sensors caused the stalling and misfire issues, but they said the sensors and transmission issues were not connected. The two sensors ran me $600 including a timing belt since they have to pull the whole side of the engine including the timing belt to get to one of the sensors. Hope this helps, let me know if you need any more info.
