HELP water pump not pumping water right?

We just got this house and I am going to be moving out tomorrow for the sake of my animals if we can't get this fixed and know what wrong. I talked to the land lady and she was too busy to help and a 24 emergency plumber who really didn't know what was wrong. I went to fill up my dogs water dishs and no water. So I turned off the well pump power and reset everything and it ran for a secound or two and slowly the water was no more. So I turned off the pump for a few hours tried again and it seems ok but is this going to happen again and why did it happen is my question? I have a animal rescue so water is a MUST. The water pressure I have noticed is a little messed up. If I run the hose outside for the horses and try to use the sink in the kitchen at the same time its not very good at all. Over all I am really not happy. We can't get propane because of code problems still and now this. Propane I will do without for now water I will not if I can't figure this out tomorrow I will leave...
