A bad diode or a short in the alternator can cause all kinds of weird problems. Casper posted a TSB (06-2-9)about the late model Mustangs having problems with the same thing. Also might want to check and be sure the plug connections aren't corroded or loose or anything.

Also found a thread on the Corral where someone else was having a tough problem with the same thing.
