So, I replaced the extremely worn voltage regulator and voltage picked up to 14.2 ish. Still wanted more so I replaced the battery cables, alternator to starter cable, and main grounds. Voltage now reads around 14.35 and peaks at 14.5. Surely the alternator cannot be the problem.

I changed the voltage regulator in the instrument cluster and the engine still loses power.. I realized that the engine loses power when it gets hot.. temperature gauge is just past the half way mark.. This means it IS the hall sender, yeah?
