does the engine crank over or just click when you try and start it?
how are the dash lights? are they bright or dim? it sounds like you probably lost an alternator and you battery started discharging till it quit on you. Have you looked under the hood and made sure you didn't throw a belt.
See if you can jump start it, if it starts see if it will stay running when you disconnect the negative battery cable that will let you know if your alternator is charging.
keep me posted, if it jumps but the alternator isn't charging you will not want to drive far as it will just be running on battery power and it will allow unburned fuel to build up in the exhaust.
