<VV> I'm thinking maybe the starter motor...

[Hugo Miller]

I would vote for the latter. If it's a mechanical fault, there is no 
reason why it should only happen when hot - especially as the starter 
has more work to do when cold. I've experienced it on a number of 
vehicles - the most embarrasing being a 10 litre diesel in a double-deck 
bus. You would swear the battery was flat - but leave it to cool down & 
it will spin over as good as new.
But why - and indeed how - would a winding 'fail' when hot?
