Try cleaning the battery terminals really well, and what are the ages of the batteries? Mine would do the same thing I cleaned the terminals and it was fine. I recently was having problems with it not starting when it was cold out like 20 degrees or colder. Pulled the valve covers off and replaced all the glow plugs. She purrs like a kitten now. The diesel engine needs a whole bunch of amps to crank if its not getting the juice it needs it will be slow to start.
