Are you using lead-free solder or leaded solder?
You will need to leave your iron in contact with the component for longer with lead-free to ensure sufficient heat transfer to the surfaces to be soldered. A lot of people turn up the iron temperature to compensate. However, this is the opposite of what you want to do and is more likely to cause a dry joint by burning off the flux.
In the worst cases, a dry joint doesn't bond the two surfaces together at all and you can simply pull them apart leaving a powdery solder lump. Otherwise a poor joint will cause the problems you describe - i.e an intermittent connection.
The first thing to do after soldering is to check the joint integrity by pulling on the joint. A good joint should have a shiny surface with a concave surface. Don't be shy to heat up the surfaces before applying the solder - you will quickly get the timing right before you melt the components!!
