Car Dies While Driving

[josh044]

I've been running into this issue intermittently.

Here's what happens.

I'll be driving, it dies when my foot of the gas as I am coming to a stop.

At this point, the car won't start up again without a jump. A jump will get me going fine again.

Here is what I find odd.

I went to Autozone, they tested by battery and my alternator. The battery was 100% good, the alternate passed, it was a touch low, I think at 13.75 instead of the 14 that was the baseline.

What I haven't mentioned is my battery corrodes like crazy on the + terminal. Usually, when this happens (after my battery is charged up again), I'll clean off the terminals and the connectors, the problem goes away.

So, I cleaned it off again last night, my drive into work was fine.

What I am figuring is that as my terminals corrode, the alternator isn't charging the battery back up and it dies. Does this sound right? Would a running car die with a dead battery?

Also, should I be concerned about the corrosion from the battery? The guy at Autozone though that the corrosion might be spreading to the alternator.

Thanks!
