Sony a100...Freezing up

I do mostly wildlife photography now although I started in portraiture. I use, do not take this as an endorsement,the Sandisk Extreme III. There are others out there which are probably as good or better.
I carry 2pcs. 2G and 2pcs.4G on a full day field trip. I also carry a laptop or PC with a 120v adapter for the car.
I photograph  birds in flight and other animals in action. I also photograph them at rest. I photograph people and inanimate objects also My main use lens is a  Minolta 300mm with the Sony A100.


All of my shots require checking focus and composition at the instant the shutter is squeezed
That requires rapid succession but not auto succession. There is a split second pause to get the setting right. This style of photography requires many hours of practice and many,many,many messed up shots. I started by photographing cars on the expressway and anything that flew. 


When I am starting for the day if the sun is good. I set my camera to aperture.  I focus on a subject similar to what I want to photograph and adjust my aperture to the largest number (smallest opening)I can get with a shutter speed of 250 . I want maximum depth of field. Then I set the auto focus to Continual and Spot. I track the subject and when I see the focus light and have the composition I want. I squeeze the shutter. I then check the exposure and adjust my settings from there.
