2001 Tahoe, No power to stock radio

[70c-10]

I was in the process of packing for a 600 mile roadtrip this weekend. I went to the store. When I got out of the Tahoe, the radio shut off as it normally does when I opened the door.

When I got back into the vehicle after shopping, the radio did not turn on when I turned the key. I pushed the power button and nothing happened and then also noticed the clock (part of the radio) has no power at all.

I checked the fuse and it looks fine (swapped it out just in case). The door chimes, windows, and dome lights all seemed to be functioning correctly.

Any ideas?

For the driver's side instrument panel, I checked and replaced (it wasn't blown):
'RDO I' - Audio System, Onstar


under the hood, I checked and replaced (it wasn't blown):
'RADIO' - Audio System, Instrument Cluster, Climate Control System

I also checked
'RDO AMP' - Radio Amplifier

any codes in the BCM ?

So I got back from my roadtrip last night.

The radio is working intermittently, with no rhyme or reason. Do you think something is wrong with the radio itself or something with wiring?

Do I need a scan tool to check? I don't have one.

This morning I realized that if I press the 'Recall' button, the display lights up for a few seconds and shows the time.

Could this be the delay shutoff causing the problem?

if this was a customer's truck I would use the scan tool to check for BCM codes and make sure communication is working between modules. Then I would check powers and grounds before condemning the radio
