Pump or pressure switch problem?

[volleybiggs]

I have a submerge pump in my well. The problem is I lose pressure to my house and I go and check the well and the pump is not running. There is switch at well for pump and turn it on and off and then it comes on and I have pressure and water. When my Blue Pressure tank is empty then I lose pressure and the pump does not come on.
Is this a pressure switch problem? Also I get lots of air coming when I do have water pressure. I check the air pressure in my Blue Pressure tank and it is good.
Thank you in advance.

Also I went and checked on the well head where the pipe comes out and I can feel the pump running so I turned it off. I never noticed before but I am guessing it was not running constantly before. I can not be sure because I never had a problem.

Air in the lines usually comes from a hole in the pipe down the well.
