Slow Turnover When Hot

[large 33]

1.9 mi fitted, runs well no other problems but when the car has been driven hard not for long 5 or 6 miles turned off and restarted it only just turns over.

I can drive the car for some time (not hard) stop and restart and it is fine. Any idears?

when the starter solenoid gets hot it can begin to break down due to the heat. I had this issue, a new starter should fix it. just check to make sure you have no breaks in the power feed to it.
