When you lose water for some time period but later it returns we think immediately of the following possible explanations:
By contrast with cases where you lose but then recover water pressure in the building are cases where you lose and do not recover water pressure or flow:
You'd have either no water or only very low pump output no matter what conditions in the well.
If the building water supply stops and takes minutes to hours to recover, you may have problem with the well flow rate. But the problem of lost water supply and pressure could be more mechanical: a bad well pump. The well pump, in turn, could have been damaged or hastened to the end of its life by a bad water pressure tank which has caused well pump short-cycling. Short cycling of the pump motor can burn up the pump relay control.
