Motor will turn over fast when cold but after driven awhile and reached operating temp it just barely wants to turn over. Any idea's? Im thincking a ground or weak starter???

 

you could do a voltage drop test on the cables, if that doesn't show anything a starter draw test wold be a good indication of starter condition if your charging system and battery are in good working condition either of those test should point you in the right direction. where bouts in east Tn ?
