This sounds like a fuel pump check valve problem, if the fuel is not kept in the filter and lines by the check valve it drains back into the fuel tank and causes the kind of problems you are having, you can check this by hooking up a fuel pressure guage at the test port on the fuel manifold that supplies fuel to the injectors, run the engine and shut it down, note the fuel pressure at shut down (with the test guage hooked up), walk away for an hour, come back and check the pressure, it should not have dropped more than 5 PSI You can buy a universal fuel injection pressure tester for about $25.00, cheaper than having a shop run the test. If the pressure drops you found the problem, bad news is the check valve is in the pump, the pump is in the gas tank.

hi i am dieter
here is something to try
keep some cold water with you and the next time it happens very quickly get out and pour the water on the crankshaft sensor then restart. If it starts right away without the usual two minutes than you will need to change this sensor. The sensor is easy to find you will see a wiring harness around the crankshaft pulley(the large one at the bottom the basically runs all your accessories like the p/s pump, alternator, water pump). Try to famaliarize yourself as to the location of the sensor first so that you can try to restart it within about 30 seconds.

I had a similar problem. I found the filter cartridge below the pcv valve had carboned up, and after the crank case pressurized, oil was forced out the pcv supply line to the throttle body. The idle air control valve solenoid got oil in it and caused my problem, but only when it was cold. The pcv cartridge is accessed by removing the pcv valve and the rubber fitting that the pcv valve mounts in. It can then be fished out with a pick set, and it is a pain because you can't see it, but you can get you hand back there. I hope this helps you.

hi there, i have a 2003 sonata and my car did the same. it stalled and the engine light stayed on but managed to get going again. i took it to Hyundai and it was the crank angle sensor. it needed replacing at NZD180.00 with 3 hours labour to do it. evidently they remove the front of the engine and cam belt etc. the workshop at Hyundai did it and charged 3 hours, not sure if that was excessive or not.

It sounds like the torque converter clutch. Just unplug it. It is the square 4 pin plug on the front of the transmission. Once it is unplugged and you get it unlocked, it will be fine. Just leave it unplugged, it won't hurt anything.
