Slow starter cranking once engine warmed up. Why ?

Briliant Andy - thank you very much

I will get this attended to ASAP.

Anyone got any ideas of locations that lend themselves to natural/easy earthing points between engine/chassis...?

EDIT: this problem started when the alternator and battery were changed over the weekend. Are there any obvious earthing points near the alternator which this might indicate to be the dodgy earth..?

Cheers!

And why would this problem only occur when warm..?

This another indication that there is an earthing issue, the starter motor requires several hundred amps when it is running, power is fed to the starter via a red cable directly from the battery, the return path from the starter is via the metal casing of the starter to the engine block, then via the engine earth strap to the chassis, then via the chassis to battery via another earth strap!
So if any of these earth straps are missing the current will flow via any other earth path it can find.
If the engine has recently been out it is possible that an earth strp has been forgotten.
I forgot to refit one on a mini may years ago & the return path was the throttle cable, which whent into melt down - causing said burning plastic smell.

So check your earth connections & if in doubt add another from the engine block to a clean paint & rust free place on the chassis.
