Ok I have an '89 Jeep Wagoner Limited (XJ body style). I am having problems with losing power at the ignition switch. If I disconnect the battery and hook it back it up and turn the ignition to the on position for 25 minutes I get power back and the Jeep runs. Then without warning of any kind I will not have power again and have to reset it again. I've replaced the starter relay (that the battery connects directly to) and the resistor and 1 fusible link that comes off the starter relay. Just dumbfounded and can't figure out why this happens. I haven't put it on a diagnostic machine cause I was told without an engine light coming on there won't be codes to diagnose. Anybody have any ideas?
