Intermittent power issue

[Trainerdude4]

2 days ago my jeep 2006 Sport model didn't start. boosted it and ran it for about an hour and turned it off. Next day it started right up and I drove it 20 minutes for dinner. Come out after dinner and same issue...but it won't jump start...Auto company checked battery and Alternator and both were good. There was no power at all to the vehicle, no lights inside or on the dash...made no noise when trying to turn it over. Get towed home and this morning I go out and it starts right up again...so I am looking for suggestions as to where to start looking for this issue.. Thank you.

How old is the battery?

Clean battery terminals and ground points?

Original PCM?

Battery was replaced less than 2 years ago by CAA.. I haven't checked the battery terminals or ground...yes to the original PCM as far as I know. I have had the jeep 4 years.

Might want to have a conversation with Mark at @Wranglerfix www.wranglerfix.com to see if he thinks it is a PCM issue.

Just checked out the site. I hope it's not that. don't really want to drop $1000 on a single part, but I guess I may have no choice.

Well let's do some diagnostics before firing the parts canon. Clean the battery terminals. Monitor your voltage especially when cranking. Clean your ground terminals. Maybe pull the plugs on the PCM and inspect for corrosion.
