<VV> Starter keeps cranking

If its any consolation, my 64 covertible used to do the exact same 
thing when it got too hot. When I bought it, unbeknownst to me, the fins 
were choked with leaves, and after 20 miles it would overheat. It would 
stall if you had to stop at lights and refuse to restart till it had 
cooled down. When you tried to start it, it would keep cranking and I 
had to disconnect the battery terminal (thankfully it was quick release) 
to stop the starter. There is a clue however - when I reconnected the 
battery, the starter behaved normally. So disconnecting and 
re-connecting the battery made the problem go away (till the next time)
I never got to the bottom of it - I blew the leaves out of the cooling 
fins to stop it overheating & that solved the problem.
