Sounds like there is a bad ground wire. Need to find all of them and make sure the connections are cleaned.

OK, that solves the wiring problem- did the hard start when hot problem go away? If not, I would guess something is not adjusted correctly with the carb- did a pro do it?- or it is vapor-locking- make sure all fuel lines are clean and protected from heat- and the carb may need to be protected from manifold heat, too-

Try jumping it to get it started, then disconnect the neg. cable at the battery, if the car still runs, then your alt. is working fine...it sounds like a short in the wiring to me.....hope this helps
