Electrical problem!! windows, radio, lights on dash, relays clicking...

My power windows and radio randomly shutoff and come back on while driving along with blinking dash lights sometimes. sometimes when they come back on i hear that single chime that sounds when you turn your key on. tranny shifts weird when everything comes back on also. it's almost like the truck shuts off all electrical power while driving down the road. to get the power to come back on i can: tilt my steering wheel up and down and lock it abruptly, take the panel pff below the steering column and hit the fuse box, hit the top of the dash above the radio, or pull back on the parking brake handle and let it spring back. not all of these methods work at any given time. i just have to try and see what works. sometimes none of these methods work.
any ideas what this could be?

You guys should really learn to post the yr of your truck when you ask for help (Major electrical revisions happened in '01)

ANY yr truck will suffer from low voltage and bad batteries. You should check Both.

Poor connections (both + & - ) can also cause voltage drops. Clean, Grease & Tighten ALL battery cable connections.

If you have an '01 or above w/ a Trans Temp Gauge in the cluster and a Digital Odometer, take a look at this connector -> POTENTIAL ELECTRICAL CORROSION if your truck is like mine......

Water, is the Fusebox wet? The GEM module above it? The lower corner of the windshield can leak on your electronics.
