Can you help with our well problem, please?

We seem to be having a problem with our well/water system where water intermittently goes out for a short time (about 30 seconds). I'm not sure what the likely problems are, and would appreciate your help diagnosing the problem so I can (1) repair it, or (2) figure out who to call for a repair. Details/my observations thus far are inside.

So we've lived in our house for about 3 years and never had trouble with our water supply until now. Lately, every other day or so (with varying frequency), our water goes out for about 30 seconds before coming back on.
Our system is somewhat complex, but no worse than average. We have a well (I think it's a bit under 200 feet deep, and when we bought the house, we were told it exceeded 5 gpm, which is pretty good in this area allegedly.) From there, we have a large (bladder tank (I can't recall the size), a filter, and a water softener.
I've attempted to diagnose our problem and made a few observations-
1) The pressure switch appears to be function properly. Currently, the cut-on pressure is ~35 psi and the cut-off pressure is ~50 psi.
2) When the pressure switch kicks on, the pump runs for a little while (30 seconds - a minute, maybe?) and the pressure is going up, then cuts off for a little while (again, maybe 30 seconds to a minute) and so on, duty cycling until the cut-off pressure is reached. I don't THINK this is normal or used to happen.... Is this a thermal protector switch?
3) I've never been able to observe the pressure during the service interruptions, but my guess is that it drops.
So what are the likely problems? Is our pump on its way out? Is our well not producing like it should? Or are these a red herring for a problem further down the stream? Are there other things I should check?
Thanks in advance!
