i can drive all i want but when i cut my xar off it will not crank for 20 mins or so and when i wait and let it sit it will crank right up what could be the problem

Welcome to the forum,sounds like the starter,"heat-soak" issues although heat soak usually lasts for an hour or more to cool down the starter. Engine heat soaks into the starter and expands the armature which binds it up and won't allow the starter to turn until it cools down....common issue on some vehicles.Good luck,Bobby :D
