When driving the car acts like someone turns the key to off. Sometimes will start back up after entering the key-less code. What may it be?

This sounds like the crankshaft angle sensor is going bad which is common. Here is a guide to help you see what you are in for when doing the job and the diagrams below you show the location for your car.

Check out the diagrams (below). Please let us know what happens.

While driving, sometimes even as short as thirty seconds, my engine will shut off. It is usually fine and does not shut off if the weather is below freezing, but the weather is getting warmer and it is getting worse. When the engine shuts off I turn off the car, put it in park and try to turn it back on again, nothing. The engine does not even turn over and I have to wait approximately two minutes before my car will start again. The other day it was only about forty or forty-five degrees out and it stopped. As soon as it started again it stopped. Finally it started but shut off on my four minute drive home.

Scan for codes and check fuel pressure with a gauge.
