Does anyone have any idea what's causing this?

What is your question?

When I idle up or rev the engine at all I lose all interior g acuges accessories power to the windows air blower all interior lighting and not sure what else I lose but when I let it idle back down it all comes back. So anytime I take off I lose all electrical operation of pretty much everything. This started this morning driving down the highway all of the sudden my stereo quit working then I realized I lost gauges and all. Soon as I stop it all comes back. Or I can just coast in neutral and it all comes back as well. Guess I'm going to get back out and try and figure this out.
