intermittant power lose to dash, windows, wont crank,
 

on My 96 STS, I had the car in storage over the winter, since I got it out I have an intermittant power lose that effects the dash, power windows, trunk and fuel door acuators, the car will not crank, and the radio and climate control don't work. If the car is running when it happens the car still runs with reduced power. The only thing that gives me any clue at all, Is once i had the key on and tapped on the relays on the drivers fender and dash came up and the car cranked, but the radio, windows, trunk and fuel door still did not work. All fuses and body ground to engine is good.
Any Ideas out there? Thanks:)
