If the check engine light comes on, then codes are stored. Get the codes read. Don't ask us to guess what codes are stored

Any time the check engine light comes on the traction control will be disabled and the light will also come on. Start with scanning the engine computer for trouble codes to see why the check engine light is on.

If the check engine light comes on first, then the engine dies, check the computer for trouble codes.
If the engine dies first, normal for the check engine light to come on.
You will need to figure out if the engine is loosing spark or fuel or both.

The check engine light may come on later. When the check engine light comes on the computer in your car logs a code. This trouble code may or may not cause drivability issues. The computer in your car always tries to fix the problem. If the check engine light is not on, there is not a problem. It may come on later if it detects another problem. Changing the battery could have fixed some problems. The ground system on the cars cause a lot of problems for technitians. If the trouble light is not on, don't look to spend a lot of money to look for problems that the computer is not picking up.
