Unfortunately, I don't have a great answer for you. I saw the same issue in regards to my temperatures appearing to always be in range and the problem growing progressively worse until an override was required for almost every print, (with the only consistent exception being that it always worked on the first print after a restart of the machine). I replaced the circulation pump, but, it only had a marginal and temporary impact on the issue which probably just coincided with the intermittent nature of the problem. I then replaced the heater and the problem became less frequent, but, I still saw it on an intermittent basis. I then flushed the coolant lines completely about half a dozen times, which, also seemed to have some impact as eventually the problem disappeared altogether.
Since then I've suspected it could have been two problems - an intermittently failing heater and a problem with the coolant loop itself, (potentially with trapped air), that when both started to occur at the same time, resulted in the eventual need to override regularly. That said, the temperatures appearing as if they were always in always in range was probably the most puzzling thing. I also could not identify any external factors like the room temperature and humidity being an issue as they have always been very consistent.
In regards to the machine hanging during the auto-startup and circulation process - I never had that happen. Do you have to hard power-off the machine to get it out of the circulation state?
If your issue is temperature related only, I would personally start with flushing the coolant loop a number of times and doing everything you can to ensure no air is trapped somewhere where you can't see. You might then consider replacing the heater and / or circulation pump as, (insofar as I can figure), they are the next highest provable and lowest cost components that might fix the problem. For my issue, the only other thing I could think of after that was the mainboard which is something I wanted to avoid altogether for obvious reasons.
