There are many cause of this, but the primary reasons are in the pressure tank. The tank MUST have residual air pressure of around 27 psi to drive the water system. To analyse further I need to know what kind of tank you have and what air pressure is in it when the water ceases to flow. I need to know what pressure your pump starts and if the tank feels heavy (full of water) when the pressure is low.

What is the best water pressure for residential?

"Best" is a matter of opinion. The "best" water pressure is one that allows you to use the lowest possible pressure to allow proper function of all your fixtures. This reduces the stress on all of the pipes, fittings, fixtures, and appliances that require water. Typical residential water pressure runs between 30psi and 80psi.

Can you have too much water pressure in a residential house requiring a pressure release valve?

The water pressure in my house is about 140PSI. Which is definitely dangerous. It happens more often than you would think. What happens is a city will use water supply lines which are too small for the water requirements. Therefore, they have to increase the pressure. You wouldn't want a pressure relief valve, because then if the pressure was too high, it would just spray water everywhere to release the pressure. You would want a pressure regulator installed, which is what I am working on for my house right now. Just to let you know though, you may have to get a thermal expansion tank for your water heater if you don't have one. See, the new pressure regulators have a check valve in them, which prevents water from traveling back into the city pipes once it has gotten into your house. When your water heater heats the water, the air bubbles in it expand, which increases the water pressure, and will probably cause your pressure relief valve on your water heater to blow. You can get a cheap water pressure meter at any improvement store to check it out. 50-60 PSI is ok. I would say you could take it up to 70 or 80 PSI safely.

Excessive pressure may damage pipe joints and internal parts of cheap faucets. The old PolyB pipe is very susceptible to breaking under excess pressure. In most cases, I see no reason for house pressure to be in excess of 50 psi.
