These types of problems are very difficult to diagnose because of the intermittent nature. I hear the pumps are a problem with these, but instead of pressure, you might have someone check the amperage draw of the pump, this can indicate a failing pump. The pressure will probably be OK, unless the problem is occurring. Have any trouble codes been stored?
