You'll need to check voltage drop --- AND resistance (Ohms). High resistance would lead me to check connections for corrosion... tight secured terminals... etc. Then if that all looked good then I'd be yarding the starter for a load test on it.
Now --- you may also have an issue at the ignition switch / wiring to it/to starter. So after you've cranked it 3 times or so --- I'd be feeling for heat in any of the wires out of that switch. Just gently put your hand around the bundle and see if there's a hot one... 'Cause the switch could be breaking down --- or a corrosion issue or connector that's loose etc. Might carry the load once -- then heat up and go apoplectic.
