a battery will only last five years, as the new tin/antimony alloys (no lead anymore) have a "knock off label" on top of the battery indicating the date of it's first charge....three years old is pretty old now, five years old is a grandpa...sounds like you're trying to get grandpa to do the heavy lifting here....Batteries will degrade 10% per year, that is to say they will stop accepting a charge 10%/yr. get a NEW one and your troubles may be over ...if you DO clean the end of the black cable that attaches to ground with a wire brush (coarse)....like I keep asking you to do~

Does it do this when the engine is hot, cold, or it doesn't matter? If it's a random thing I'd suspect a dying fuel pump. If it happens when the engine is hot I'd suspect an ignition problem such as the control module. Sometimes they work fine when cold but break down when they get hot. HTH. -Jim

When it quits check for spark. Remove one spark plug wire and insert a screwdriver in the end you just pulled off the spark plug. While wearing heavy duty rubber gloves, hold the screwdriver by the handle close to something metal that's not painted. Have a helper crank the engine. You should see a spark jumping rhythmically as the engine is cranked. You should also hear it too. Like a snap, snap, snap sound. If not, check the coil packs, and control module to find out why you have no spark. If you have spark, check that the fuel pump is working. HTH. -Jim

sounds like a crankshaft sensor gone bad. Ifixed this problem by replacing mine.
