I really feel this is somehow to do with the DHCP client/server interaction between the two devices. I have even tried running the modem non-bridged so that there is a dual NAT situation which gives me a very similar result.
Similar good or similar bad? If DHCP is the problem, it can only be that the ISP is throttling the link in the absence of whatever it is the modem does that the MT doesn't. All DHCP does is provide an address to your end, which is still happening. Throttling is usually down to way lower rates than 20Mb/s though. The obvious thing to try here is a different brand of router. If it's something to do with the router not responding the way the ISP wants, then any router will have the same problem. If some other router works fine, then it's MikroTik-specific, The most interesting part of all this is the delay. It works well for quite a long time, then suddenly slows down. Then you reboot everything and it's all good for a while, before slowing down again. That smells to me of something filling up or running out. Is the time from reboot to failure constant?
