From the sounds of it you are loosing power. You might have you battery tested. or the next time you get it running take it to the auto parts store and have them do a battery test and alternator test on your car. if that checks out to be good then let me know and we will go into another direction.

Welcome to Fixya
You might have a bad headgasket that causes a misfire and rough idle. Check the spark plugs if it is wet with oil. If plugs are wet with oil, then fix for that is to replace the valve cover gaskets and spark plug tube seals. Run a scan tool and see if you will be getting error codes. Provide the codes to me and i will help you fixed the problem.
Thank you for using Fixya!

The check engine light comes on when a part of the cars emission system has a problem it could be a loose gas cap to needing a tune up to catalytic converters going bad. If you take the car to a local Auto Zone or Advace they can hook it to a scan tool and help give you a general idea to what is going on.
