The most likely problem is your USB connection if it works sometimes. Use a connection on the back of your computer (if you have a choice of front or back) and don't connect through a hub.
Another, less likely, possibility is that your antivirus or firewall is blocking the connection.
You may also have another app on the computer that is hogging the USB bus (I know that's redundant) or something that has killed the AppleMobileDeviceService. Open Task Manager when you have a problem and see if this process is running.
