Just saw one like this a few months ago where it would idle or run for up to an hour or more before it would shut off. It was the ignition module. Try that first.

MINE IS NOT THAT BAD. YET. IT COULD BE A FEW THINGS I WOULD START WITH THE IGNITION CONTROL MODULE, THEN MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR. OR EVEN YOR MASS AIR FLOW SENSOR WILL MESS WITH THE VACCUM, WHICH THROWS OFF YOUR VEHICLE CONTROL MODULE.MORE THEN LIKELY ITS OUR I.C.M. I'LL LET YOU KNOW HOW MINE WORKS LATER THIS EVENING!

If it's not your battery then it could be your alternator. to be sure, disconnect the negative cable from the battery while the engine is running, if it dies then it's your alternator.
