Like Wiseman said, check your cables. I have a 2008 ProStar, and I can tell you the cabling was a mess. The main cable going to the starter from the battery had nearly a foot of exposed copper, that is how it left the factory. All of my cabling on this truck was sporting bare copper under the chassis and all of it was green. I had to replace all of it, including the grounds, all of it, around 80 feet of the stuff. How this passed any kind of QC inspection is beyond me, I'm lucky the truck did not catch fire, it was that bad.

After inspecting the cables I would check the starter, may be time, they do not last forever.
