BB corvette starter issues


Second starter in three years with a hot start issue,from what i have been told its not unusual for the 454 to have this issue,starts without a issue cold whirls over fine the battery has been load tested and shows OK,take it for a spin get the engine to temp shut it down at the next stop and if you have to start it rite back up it grunts to turn it over and it will start but the starter is laborsaving badly is there a fix other than stater after starter replacement.Rob R
