the car runs great.. in good condition.. all i've had to do is oil changes and get a new battery a few weeks ago... anyways, while driving today i was in drive in an idle slowing to a red light, then i had to accelerate... but suddenly had no response in the engine, the car slowed to a stop and began "rumbling" ...as if i was running out of gas... it then died, it starts right up, rumbles for a few seconds, maybe moves an inch or so if put in drive, then dies again....

what could this be? ...i'm not that educated in vehicle maintenance

Sounds like a bad fuel injector Could also possibly be a bad fuel pump. Take it to a shop to verify.
