put a volt meter on the battery when the car is running, it should read 13-14 volts if not your altanator is bad.

Sounds like your alternator or the voltage regulator. Probe the harness on the alternator, make sure you're ignition wire is hot. I had the same problem recently, turns out the ignition wire wasn't working. Just a thought.

Good luck.

Definitely sounds like an alternator problem to me. You can probably take it into your local auto parts store and they'll test it for you for free. But by the sounds of it, it is your alternator. Having power loss is a very common symptom of a bad alternator.

I too have recently had a similar problem. The altenator is really easy to pull just two bolts a wire harness and a belt. Takes all of 10 min. Take it to your parts store they will be able to test it right there.
