You may need a new battery and possibly alternator. Load test battery, check alternator voltage output. If all that checks out have a look at the condition of your spark plugs/wiring.and vacuum lines. The last idea could be gas filter. If you have not had a tune up in a while it might be a good time to do so. Good Luck!
