Sounds like a loose wire might be grounding out the electrical system. Check all wires under the hood for good insulation with no cracks or worn spots on the wires. Possible voltage regular problem so check that also.

Right Porsche, the Chevrolet's have a problem with the main wire that feeds the power distribution box from the battery, I have had to repair a bunch of them, most was at the battery connector.
