Robert,
This is a dead givaway (no pun there) that you have a bad or no ground between the alternator and the engine block.
Pull down the stone shield under the engine. Feel at the lower read of the alternator for a stud terminal. An 8mm bolt holds a ground wire (usually blue) onto the alternator case. If you were to trace this wire, it enters one of the two harnesses that wrap under the lower crank pully at the front of the engine. The wire exits on the driver's side of the engine and is attatched to a common ground bolt down along the front driver's side of the engine. If you have trouble locating it, trace the wire from the battery/coil to it.
When I replaced my wiring harness, I had to loosen this alternator connection to take off the harness from under the engine (or so I thought).
I failed to secure and tighten that ground wire. Sure enough, after about 45 minutes, the dash lights came on, the headlights dimmed and the engine died.
