My problem started yesterday morning when I could not start the truck. I found that I had blown a 20A fuse in the Power Distribution center for the starter. I replaced it and the truck turned right over. I went home and looked for loose battery connections or bad grounds that may have caused the fuse to blow, but found nothing obvious. The truck started fine a dozen or so more times until this afternoon until I had to replace that same fuse. Has anyone ever experienced a problem like this. I was thinking perhaps this was the starter's way of failing rather than the usual ticks and free spins. Any help is appreciated.
