I am a Jeep CJ kind of guy
I copied this answer from a 1999 cherokee question I answered previously.
I've been here quite some time, I read up on a good bit of the problems dealing with the other jeeps. Many times I have seen a new crankshaft sensor fix the issue (in the forums)
I have a friend in ar, who had the same "Wait 30 min-1 hour" and it would bust off and run.
He's sorta "Tight and lazy", and had his trips measured and stop timed, so that his rig would continue to get him around locally!
I suggested throwing the part at it, before he took it to a shop. His wife managed several apartment complexes and he was "Elected" maintenance man. Only with his mechanical (non-automotive) skills he was able to do this job himself.
