Is your 'battery light' on? If it is, check that your belts are in good condition. More likely the alternator is faulty. You can have it tested (usually for free) by most repair shops and auto parts stores. If this is a new style cougar (the little one from the late 90s) expect to be charged at least 2.5 Hours for installation of a new alternator unless you want to do it yourself, which may require a lift or having two elbows on at least one of your arms.

This happened to me on a road trip in my 84 Cougar. It was a long time ago, but first make sure your belts are tight! But I believe you may need to replace the alternator. If the battery is old, its cheap insurance to do both.
