Based on your reported observations your starter does have a problem, it 
is not getting the current it needs. I don't know where you are 
measuring your system voltage but IF is is across the battery then one 
of three things is happening.

One. The starter is shorted and when you close the solenoid 300 to 500 
amps circulates through the battery dropping the terminal voltage to 1 
volt. (very not likely).

Two. The battery has an internal, intermittent and temperature dependent 
open in one of the cells or intercell connections.  (not likely)

Three. One of your connections is corroded and when things get hot it 
expands and opens. (My first bet) Remember, when you heat a fastener 
everything gets bigger, even the gaps.

If I were you (poor you) I would check the ground connections between 
the engine and  battery and then all the other high current joints. Are 
your high current ring terminals crimped and soldered or just crimped?
