MBP red cap unreliable

Hi
My old red cap MBP has been running for many years. I think mine is one of the first ones out there.
The internal storage was replaced pretty fast with a ATP NAND DURA 1GB.
This year I had two crashes - the last one today. The device became unresponsive on network and power cycle did help, but only after a couple of retries. The unit is flashing red on boot and then stops flashing and nothing more is happening.
First I tried with another PSU since it’s the second time this year but didn’t help. A couple of retries with the original PSU did help (raspberry pi PSU)
My data seems to be good. Could this be a hardware problem or maybe storage wear?

The Lic# (mbpro-xxxxx) can you give you an idea of of how old the unit is?
What does the Storage say under the Information tab>System?
So the data still comes in ok but the unit itself is crashing/rebooting/not powering up properly?

Yes I think all my data is good

I do monthly backups, and yesterday when it happened again, I did a backup immediately without any issues.. Also I tried to do an SQL export in minutes resolution, but it failed. Unfortunately I can't give you the errors from the log.

There's nothing visually obvious with the USB stick.
Power Data? V/mA are up a little but not sure if any bearing? My MB Reds are 5.30V 396mA 2.1W & 5.34V 429mA 2.29W so probably nothing of importance?

As far as I remember the RPI PSU is 5.5v. I’ve been using the same PSU since the MBP was new.
Maybe I should consider to upgrade to MBP2 if the problem persists

So yesterday it became unresponsive again. The upper led light was flashing red.
After som power cycles I made it boot again with the same psu.
As I read from the manual the MBP was shipped with a PSU. Did it ship a raspberry pi PSU?

Many of the MBPro's came with Raspberry PI (Stontronics Ltd Switching adapters) PSU which were simply a +5v-2A output. Operationally I don't use mains powered adapters, everything is 12v to 5V from 1-3A, never had a power issue.
