1) when I plug the phone into my Windows PC (10), the phone will show "Use USB for" and I select "Transfer files (MTP)".
However, quickly afterward the same dialog will pop up
2) When I am lucky - and MTP works - I'll navigate through the folders on my 64GB uSD card in my phone and suddenly the phone stops sending the data. Maybe USB will have worked for 30secs.
3) When I reboot the phone, then I can reliably get MTP to work and I can copy files.
What can I do to get file transfer to work reliably without having to reboot my phone ? (I would expect this from a cheap phone)

does it indicate that the connection is stopped? (like the ding sound)
try to secure your usb port at the phone's end,. it might be loose.
does this happen when you are on safe mode?

Welcome to the community.
Based on the information you have provided it sounds like the connection is getting interrupted. In addition to the suggestions @nolramlb has provided, I also recommend you try another USB cable, another USB port in your PC, and if possible, another PC to see if the same things are happening. It will help us isolate where the problem originates.

I had a USB cable (a long one) and when I plugged it in, my Z5 gave a lot of dinging sounds. So I replaced it.
I then used another USB cable. However, I noticed last night that the transfers failed after a little bit of time.
I tried fiddling with the cable, slightly pushing it around the connector, to see if it was lose. The phone didn't lose connection though. It seems like a solid connection.
I haven't tried booting into safe mode. I simply rebooted the phone and after the reboot I was able to connect without issue and transfer a 1GB file.

I'll try another USB cable and the USB ports on the other side of my laptop, the next time I run into this problem.

I suspect two things:
1) when I want to copy files to my phone *and* I have Android Studio running, the probability of successfully accessing the SDcard is reduced.
2) attaching the USB cable between phone and computer, whilst the phone is locked, results in increased probability that accessing the SDcard will fail (obviously after unlocking the phone whilst the cable is still connected - and selecting MTP)
USB cable itself is known working. I have seen a faulty USB cable trigger the "Use USB for" dialog repeatedly. My problem description is not that problem.

I transfer 2GB+ files on a daily basis, because I do things like this
What does windows 10 see the phone as in device manager?

I am having the same issue (as OP).
Cannot transfer files, as the device randomly disconnects mid-transfer. Seems to happen more when I am navigating file tree or transferring multiple folders, but no exclusively in those conditions.
Now I cannot view all the files on my external SD. I cannot connect to transfer files at all (the dialogue to connect comes up automatically every few seconds now).
Sony Xperia Z5 Compact E5823
Build: 32.3.A.2.33 (has been the same on various previous builds since I've had the phone, usable before, this version is worse).
I have tried:
-Several different cables
-Multiple ports (usb3.0 and usb 2.0)
-Changed settings from developer options (usb debugging off/on, switching from usb configuration options)
-I've tried via Linux and Windows 7, and Window 8 on a virtual machine
-In Linux I've tried using jmtpfs, mtpfs, several other apps, vlc, clementine, ... every time I click on the device's icon, the dialogue pops up on the Z5C again and it doesn't connect.
-Restarted phone, restarted computer, double checked the versions (updated computer).
From the Linux terminal:
