I'm new to this forum and I'm hoping that someone can help me. I have an '01 with 138,000 miles (which runs great), but as of yesterday I noticed that the radio/CD player and instrument panel would shut off for second then comes back online.
This happens only when i'm driving, but never once did my engine die. The radio would just go blank for a second, the speedometer would drop momentarily then everything comes back to normal. I didn't notice any hesitation in the engine.

Any ideas? Could it just be bad fuse, battery, altenator?

Please help.

 

Could be your battery or battery cables.
