Starter not disengaging sometimes

Hey everybody I am having an issue with my dodge nitro sometimes when I go to start it the starter will continue to try to start the car even after I have release pressure on the key and the key will be stuck in the start position until I pull it back to stop position. I have heard of some dodges having issues with the TIPM power control module.Any ideas of what this could be it doesnt do it all the time only sometimes but its still annoying.Thanks for any help.
