about once per week, I try to start the vehicle and it acts like my son. It looks like its alive, but it doesn't do anything. I wait about 30 seconds and try again and it starts up like nothing was going on, but if I try to crank it immediately after it does nothing, it doesn't respond. It seems like it needs about 30 seconds to reset. It is a 2006 chrysler town and country. Any clue on this?
