Without knowing your situation's specifics, such as which version of PowerPoint or operating system, it's difficult to find a specific fix.
I did take the time to do a search on Google and came up with a few possible causes:
1. An OS limit on how many total files the system can handle has been reached,
2. An internal MS Office application limit has been reached on how many macros/images/movies, etc. are included within a document,
3. The MS Office limit has been reached on how many times the document can be auto-saved,
4. Or, a network and/or folder sharing conflict has arisen.
Regarding Problem 1, I saw references in the Google search indicating that OS 8.6 has a limit of 348 open files while OS 9.x has bumped that up to around 8000 or so. The definition of an open file, in this case, is any font, extension, macro, picture, application, subroutine, or script that the computer needs to hold an address space open in memory for. Typical fixes here would include limiting the number of active fonts in the System Folder's Font directory and keeping the number of open applications down to a minimum, among other things. I didn't see any reference as to whether any version of OS X has any such open file limits.
Problem 2, I came upon discussions in a variety of other Mac Office forums where people had around 60 macros/images/movies implanted or imported in an Office document, including PowerPoint. The applications seems to choke on having that many "features" in a single file. The fix here would seem to be to reduce the number of such instances of these external files called within a single document.
Problem 3's references were few but to the point: turn off the auto-save feature in the application's Preferences. It appears that some Office applications will only auto-save up to 60 copies of a document then no more. If auto-save is a feature that must be enabled, due to operating policy at your location, then manually invoke the "Save As..." option frequently, slightly changing the name of the document each time. My reference also showed that manually saving as another variant of the document type would allow work to be saved without major loss.
Finally, Problem 4 can be overcome by not working with the file directly from within shared folders or across network connections. Using the Finder or other copy utility, copy the file from the network location to your local HD, work on it and save the changes there, then use the Finder to put a copy back onto the network share. This step usually fixes the majority of network related issues. This type of problem was quite common in the early days of Macs trying to access non-Mac networks, but in some circumstances, it can still pose a problem today.
Hope this info helps. This is by no means an exhaustive, all inclusive list of potential problems and fixes. This is just what I came up with after about five minutes of searching Google.
Good luck.
Steve
