Wells, Sump Pumps and Septic Sewage Systems - Help No Water

My husband and I purchased our home 2 years ago. We have always had city water and know absolutely nothing about a well. Our water pressure has always been great but in the last 2 months I can be taking a shower and it will be going good and all the sudden the water starts slowly dwindling down to nothing. I turn it off (which is very annoying when in the middle of a shower) and wait a few minutes and filnally the water will come back on. I notice that it usually does this when the water hasnt been used in a while. It also sounds like the pump is possibly in a bind sometimes when it kicks back on. Please if you have any information that would help me it would be great!!! I can't afford to pay for someone to come out and I can't afford to not have water either!

This takes two people, but if you look at this post:

You will see what is supposed to be happening. Then you should note what the deviation is before you can figure out what is wrong. If you don't have a gauge, then use a tire pressure gauge on the (we hope) easy to find tire valve.

Once you have an idea, look at the rest of the sticky the post came from and/or comeback and ask again.

One of the most common issues I've found is that the pressure switch dies or gets clogged. I've had two pressure switch replacements since I built my house 20 years ago. Another common issue is the whole house water filter if you have one. This usually just slows down the water flow all the time, but it's worth checking.
