Check the wiring down by the starter. Make sure everything is clean and tight. If you still have the negative (-) battery cable bolted to the exhaust manifold, move it to the power steering pump mounting bracket. Power comes in from the battery. A catastrophic failure like this is going to be battery related. HTH. -Jim
