I have exactly the same problem. I tried SaveDefinitions->True and in one plot it worked, and in the other plot I got "Initialization timed out >>". I don't care how long it takes so long as it eventually generates the plot. I had to ask for help on how to generate the plot - I have , PlotRange -> All, PlotPoints -> 5000 to ensure no aliasing problems in the plot. Hopefully this is trivial!
Thanks.
