What's the problem?

2003 Chevy Silverado. Twice now, while driving down the road, radio dies on me. Two days later truck won't turn over. Jump it off and all is well for up two weeks. Then it all happens again. Had battery checked, starter and alternator checked out. What am I missing? Would appreciate some advice.

    If your truck wouldn't start, but then starts right up with a battery jump, you must have

    a charging problem

    cable/ground cable voltage drop or corrosion

    a slow parasitic drain on your battery.

    As the battery depletes itself, things will start to go awry in the car.

    So, first off, if I were you, I'd clean up the cables, load test the battery (the best way to test it) and then test for a parasitic drain. You should be drawing off no more than say 50 milliamps. If it's approaching 300-400 mA, then you have a drain problem.
