I have run into this issue as well.
I am now in the habit of opening Mobipocket on my main computer and checking every new book after download. If the cover, or other information is missing, I can often add it with Right-click > Get eBook information. That usually does the trick.
I also change the title of all of my books to Author-Title using mobi2mobi. That gives me a last chance to see if the cover will show up. If it does not, you can add the cover using mobi2mobi.
I hope this helps!
