Instrument Cluster and AC not working

I have an issue where the instrument cluster (tach, spedo, fuel, temp, door open indicator, etc) and AC stop working. It only happens under the following conditions and can be reproduced easily. All fuses have been check and are OK.

1.No Gauges
2.Remove and replace Multi-Fuse 20 (which is new and good)
3.Gauges and AC work
4.Drive car or start etc. and everything works fine
5.Power off car for exactly 1 min. or more with doors closed
6.Start car and no gauges or AC again
7.If wait less than 1 min. (tested 30 sec. to 59 sec. ) to restart the car and all gauges and AC continue to work fine

Looking for suggestions on where to start diagnosing. TY

Nothing yet and I have replaced the body ECU and gauge cluster and the problem still exists. I am continuing to trace and troubleshoot, but no luck yet.

Thanks for the update. I'm continuing to troubleshoot and experiment. I'd like to fix it myself, if possible. If I find anything out, I'll let you know.
Being female, I really don't want to go to the dealer... they are, unfortunately, my very last resort.

Finally gave in and took the car to Toyota dealership for service. It's been there about 7 weeks now, with over $2,000 in inventory parts that need to be returned because they tried and tested different things. It should be ready next week so I'm told. I'll keep you posted.
