I will let you know what Sony says when their service manager calls me. Your experience is pretty similar to mine except for mine actually shutting down. If you read other posts on other forums some people have multiple copies of this camera for their businesses and one copy out of their cameras is exhibiting what we are currently experiencing.
In my opinion there are some lemons out there and I therefore will be pushing Sony hard for a replacement camera.

There definitely seems to be some overheating issues with the A7IV. After watching a pile of youtube videos about the camera while I was waiting for mine to arrive (my first Sony camera).. One of the first things I changed was setting the "Auto Power OFF Temp." to High.
Mine also got quite warm just going through the menus, which seems a little absurd. Didn't shut down from that though since I had already changed the shutoff to high. (otherwise it probably would have)
Did a video test yesterday. I only have v30 sd cards atm so can't test the higher bit rate modes. My test went as follows..
Screen closed. ( I tried it this way since the room I had it in was only about 60-65F degrees, if that )
XAVC S 4K
60P
140 M 4:2:2 10 bit
Stabilization set to active
It recorded 50 min 47 secs before it shut down
Cards were not full and battery was still over 40% so I presume it shut down from getting too hot. I did use my infra red temp gun on the body about 10 minutes before it shut down and the hottest spot I could find was around 109F, felt warm but not hot to the touch.
I'll try it again today maybe with the screen open. I just figured since the room was so cool that having it closed would be a better test. I mean if you put the thing in the fridge it would probably not overheat (I would hope), but that is not real world use for most people.
What is actually causing the heat? The processors, sensor, combination of things probably..? Whatever it is hopefully they can get some fine tuning done and improve things with a firmware update, soon.. 🤷🏼♂️
I had hoped since this is ver 4 of the camera that this would be sorted out by now, but I guess it is a new higher 33MP sensor now, so there is that to deal with.
If yours is overheating and shutting down that fast in a normal temperature room, I'd be tempted to return it for a replacement or something. That does seem to be worse than average from what I have read.
I'll try and do another test on mine today...
