Power cutting out while in sleep and sometimes while in use

Mac Pro mid-2012
This machine has been cutting out periodically for about a year.
There are two problem areas. Firstly it cuts out when put to sleep. Secondly it cuts out randomly, perhaps after several weeks untroubled usage. It's very unpredictable in this respect. To get round the first problem I changed the energy save settings to let the screen sleep but not the computer [moving the pointer to 'never']. Obviously this doesn't solve the random cut-outs.
Apple had it for two weeks. They found nothing and suggested a software problem. I think that's wrong. It's baffling and resetting the PRAM/SMC hasn't worked [I did this myself and am certain Apple techs did the same as the first order of business] but since reading the advice dispensed to iMac owners with similar problems I now suspect something more serious.

iMacs are not Mac Pros but is the weakness likely to be the same [logic board/power supply]? I'm guessing things will get worse over time so naturally I'm quite anxious to solve the problem. It's unfortunate I'm very much a non 'techie' type, and that these things are often too complicated to simplify for people like me, but with things as they are I'd just be terribly grateful for some advice. Thank you.

Apple suggested a software problem. If it is I don't see where it's coming from. Resetting the PRAM/SMC hasn't worked [I did this myself and am certain Apple techs did the same as the first order of business]. It's baffling and it was only when I read '''‘Apple Stumped – iMac shuts of randomly, daily to multiple times/hour’ ''' I began to wonder if I might have a terminal problem on my hands.

I bought a used Mac Pro [mid-2012] A1289. According to the seller the machine had been cutting out for many months [hencethe good price I got it for]. Two visits to Apple and various tests had proved fruitless apparently.

The pattern established was that it cut out when put to sleep or randomly after several weeks untroubled usage. Changing his energy save settings to let the screen sleep after a period but not the computer solved one problem but periodic random cut-outs continued.

I've assumed Apple – who had the machine two weeks according to the seller - would reset the SMC as a matter of course. Although I knew about the faults it only occurred to me later that it might be something serious. So far I’ve run the machine a few days but, like the company, I’ve found the problem hasn’t been replicated.

Then I read '''‘Apple Stumped – iMac shuts of randomly, daily to multiple times/hour’ ''' along with the answers and once again I began to wonder if I might have an expensive problem to remedy [though power supplies are cheaper than logic boards].
