Strange electrical issue

My gauges reset and I lose all power while driving intermittently. I've noticed it tends to do it when I accelerate quickly but is fine when idle or slow rolled..any info would be greatly appreciated

Have you gotten an alternator load test done?

No I haven't.. Can I do that without removing it from the car?

Most auto shops should have a machine to test it. Auto Zone I but I don't know for sure. Just to clarify, you lose all power to the car or just to the gauges?

All power and the gauges reset and then it's good again

I'd start by checking all of the basic things like battery terminals, cables, carefully check the grounds, etc.
If everything looks good, shake all of the battery cables and wiring harnesses, with the engine running, and try to replicate the intermittent power loss.

Battery terminal connections like straybullitt says. Clean an reseat and tighten.

And most inportantly do not forget the grounding areas, look them over, see if the grounding pints are loose.

Yep.
Look around the battery and radiator support etc for grounds and make sure they are tight. If any look corroded, take the bolt out, clean up the surface and tighten down again.

The cluster resetting, the gauges going all the way up and then back to normal, means it has at some point lost primary power. Last time I had this it was what seemed to be a tight connection at the battery post but was actually slightly loose.

Start there and work your way back to the junction box. Also make sure all fuses are seated tightly.
