What happens when you try to start it? Do you get anything? Clicking? Cranking? When it does start, does it fire right up as if nothing was ever wrong? Has it had any running problems? Stall out? Do you have the original alternator?

From what you described the first thing that comes to mind is a short in the wiring harness. Also check your grounds and battery cables. If it was your starter, I would have expected it to have completely died by now.
