Starters pull more amps when they get hot due to resistance. A hot starter has more resistance than a cold starter. This would strain a weak charging system.

A bad starter on an other wise good charging system would have the same effect, as it heats up resistance builds to the point where it pulls more amps than the battery can handle.
+1 on alternator or regulator. One of them are bad. If alterntor switch to 1 wire and loose the regulator
