The fact that it does start run most of the time would indicate that the problem isn't permanent damage but likely something like a bad connection. I would start by inspecting the fusible links located under/behind that black plastic cover beside the battery.

 

 

The fusible links are the red wires down on the left side. Inspect them for burnt or melted insulation and unplug and plug back in several times to clean and make good contact. The other end should have a black wire going to the negative battery post so be sure it is secure/clean/tight.

 

 

If you loosen the screws on the top of the gray metal panel you can tilt it forward to inspect the voltage regulator behind it. you are looking for burned wires which will pinpoint the problem. You dont have to remove it, but you can unplug it and plug back in to provide batter contact of the connector wires.

 

Last I would remove and replace the fuse box fuses located on the kick pad by the passenger's knee. Be sure the contact clips that hold the fuses are clean of any corrosion. Don't bother testing or inspecting a fuse as this is unreliable. They can look good but be bad internally, just replace them.
