Image processing delay
This may linked directly to an issue with the memory card or internal storage circuits.
When the shutter release is operated, the image projected on the sensor is collected and sent to the internal high speed memory of the camera called the buffer. This buffer is very fast - but not very large in capacity. Depending on your exposure settings (NEF, JPEG, NEF w/ Preview, Large, Med Small, Fine, etc.) you may be able to take anywhere between 6 and 75 exposures in rapid succession - this means 3 or 4 per second. Once the camera's internal buffer is full, it must be sent to the comparatively slow CF card. When this happens, no more shooting can take place.
A minute strikes me as being too long for this to take. I would recommend that you remove the CF card and copy the contents to a computer. Format the card by the computer to make sure that it has the capacity indicated on the label. If it is slightly less, it is OK - if it is more than that, it may indicate a problem area on the card that the camera is repeatedly attempting store data upon. If the CF card checks out OK, return it to the camera and format it in the camera. This is a very important step. Whenever you transfer pictures from the card - whether it is with a card reader or via a cable between the computer and the camera - format the card after the transfer in the camera - before taking more photos.
CF cards have dropped in price, and you may benefit from buying a new one for use in the camera. Select a faster class card whenever possible. Memory cards do have a finite number of read / write operations and you may be reaching the end of life on yours.
I hope this helps and good luck!
