My Jetta is a 1999.5, 2.0, as soon as the engine gets a little past 190degrees (on the dashboard), it shuts off. I have changed the ignition coil, camshaft position sensor, and the engine coolant temp sensor in vain. I was looking at it possibly being the crankshaft position sensor, fuel pump, fuel pump relay? But last night I realized that the engine turns OFF, right at the moment the fans should be turning ON?(Fan relay?) Can someone please point me in the right direction??? The ignition coil had a small crack on it. Could moisture have caused shorts in other areas? The car absolutely won't start if it is warm. It will only start once its good and cool.:confused:

Changed out crankshaft sensor. Car stays on. PLUS. Now it has lost about 1/4 of it power.NOT GOOD...the battle continues.
any check engine lights produced/stored?

check engine light is, and has been there. Will probably be buying a scanner to read the codes tonight. It almost feels like something is obstructing the exhaust:confused:....was thinking maybe a bad spark plug too, spark plugs are under the intake manifold on this beast.:mad:
let us know what codes come up...
edit: could be something silly, like a temp sensor reading incorrectly and shutting the system down for safety measures.
also, it appears that your car has gone into limp mode because of the problem. this would explain the loss of power. again, it's just a fail-safe for the engine...

OK, I'm at 6 codes. It had 12 before I erased the old ones. I'm using the Actron CP9575
P1426-No Definition (Mod $10)
P0300-Random-Multiple Misfire Detected (Mod $10)
P0301-Cylinder 1 Misfire Detected (Mod $10)
P0302-Cylinder 2 Misfire Detected (Mod $10)
P0303-Cylinder 3 Misfire Detected (Mod $10)
P0304-Cylinder 4 Misfire Detected (Mod $10)
I took the timing belt off when I dove in for the Camshaft Position Sensor, thinking I messed with the timing...
^^ that could very well be the problem. re-time, try again...
the 1426 could be pointing to your gas cap not being on tight enough.

Ok, got P1426 to go away. The connector for the EVAP purge valve was disconnected. Must have come loose during the camshaft sensor swap...hopefully I'll be able to get this timing problem solved tomorrow.
Thanks for letting me bounce ideas off of you leOn.
