I've had that same problem. My first guess would be the alterator. but, save your self the trouble of taking it out by first taking your battery to an auto zone and let them test the cell for you, if your battery cell is bad, it doesnt matter how good your alternator is, it just wont hold a charge, period. if its not the battery, then its definitely the alternator.

Check your alternator (it charges the battery) If it quits you are running straight off the battery and that won't last long. Also check your belts. If they are loose and slipping your battery won't get carged and your alternator won't work properly
If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good. If it stalls and dies as soon as you unhook the battery then the alternator is not good.If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good.

Yes, as long as the engine is running, so is the alternator. The alternator is actually what keeps the car battery charged.
Defective alternator or broken alternator belt.
While the engin is running remove the negative side of the battery. If your car dies, your alternator is probably bad...Of it it wasn't when you started, there's a good chance it is now.NEVER disconnect the battery or alternator while the engine is running. You can fry alternator diodes, computers in the car, electronics you have installed, pretty much any sensitive electronics can be damaged or destroyed.Take your car to get it checked. Most autoparts stores these days will do free alternator tests.

A faulty alternator will cause those symptoms. You might want to get t checked out.
Ignition timing, timing belt/chain, distributor cap... who knows without looking at it?
The positive cable between the alternator and the battery has an open circuit or break. There also is a set of wires that plug into the alternator that turns it on when the car is running. Wiring problems here can cause a alternator not to charge on the vehicle but works fine on a test stand. Some cars the alternator light in the dash causes the alternator to kick in when the engine is started. A burned out light in the dash causes the alternator not to charge.
An alternator is the part of an automobile that generates the power to run the radio, headlights, speakers, and air conditioning as well as any other electronic component in the car while the engine is running. This is different from when the engine is not running. When the engine is not running, the 12 Volt car battery operates these electronics. Unfortunately, every battery will die eventually, so the alternator also recharges the battery while the engine is running. This is a slow process, though. But unless the battery is charged, the engine usually can't ever be started.
one is most places test for free. but the easy at home way to check is get your car jump started if its not starting on its own. after its running, pull the negative off the battery taking special car not to arc your wrench on anything. if its keeps running, alternator is good. if it dies, get it replaced. if the alternator is bad, it may have killed the battery, so get it tested and replaced if needed.
You could have a problem with your alternator, which supplies electricity to the engine. That is the most common problem I've had with my neon. The other possibilities could be that the O2 sensors [pre and post the catalytic converter] could be damaged or dirty. Heres a question that could help answer the question. How long does it stay started before it cuts off? if the answer is roughly 5 to 10 minutes at most, then its the alternator. If the answer is about 1 to 2 hours depending on if your driving on the highway then it could be the O2 sensors.
