x17 R2, screen turns black randomly!

So quick history here... I'm a very techy guy so i consider myself pretty advanced with troubleshooting and typically figuring things out on my own, rarely do i post in forums but after spending over $5000 USD on this laptop i really dont want to turn it in for a refund... so here is my issue..

When i first ordered the laptop, it took a while to come in, almost 2 months, i live in Florida and this thing came from China, long wait but it was worth it.  As soon as i got the laptop, during Windows setup the screen just went black, keyboard lights stayed on but the screen went black.  Then it came back on, about 4-6 seconds it was out, weird but i just ignored, then it started happening more and more, to the point where i really couldn't use the machine because it constantly did that, luckily i was only a week into owning the machine and i talked to DELL and they agreed to send me a replacement.  Waited almost a month for the replacement but it finally came in and that's what I'm typing on now.  

Ever since i pulled this one out of the box about 5 days ago its been perfect, not a single issue, i really dont do much gaming, more work and coding so I'm typically just in Windows doing low intensity tasks, which should not be an issue because this machine should be able to handle what I'm doing by 10 fold if not more.

Today i sat at my computer and the screen and keyboard turned off, almost felt like it shut down, stayed off for about 20 seconds and i was at a lock screen, then it did it again...  i can't believe i have 2 laptops that are having the same graphics card issue (i have the 3080ti with UHD screen).  I rebooted the machine after the second black screen and it hasn't done it again.  I dont feel like i should have to hook this computer up to a monitor, take it apart etc... it either works or its broke is how i look at it.  I tried talking to DELL support last time which was a nightmare, seemed like the support folks were in India and everything was done via email, they basically spent 2 days with me going back and forth only to have me try to update the BIOS but it was a BIOS i was already using.

Anyways, if this one keeps doing this then I'm done, going to return this one for my money back and by a new MacBook which i dont want to do, i absolutely love this laptop while its working correctly (which it should work correctly always for this type of $$).

Anyone else have a similar issue/fix?
