Battery Problem?

[ferndog5150]

Long story short, at times my truck hesitates to start but it does start with no problem. This morning with slight hesitation truck started up and the clock and date were reset...this happend twice but the radio preset was still saved. Already put battery underload and checked the alternator everything checked out ok...any ideas?

I'd check your grounding. Corrosion can cause a faulty ground which maay lead to power loss.

 

I'd start with that at least.
