Does this happen in all projects? Try turning off render multiple frames. Some plug-ins don't like that setting to be turned on.
You might also check your fonts. Sometimes a corrupted font can cause huge memory problems for AE.
Yes, it does happen in all of my projects.
The fonts are fine. I just created a new project, typed a regular text layer with a Times, and even that RAM preview took over a minute. The render was the same.
Well, lookee there. Just unchecked the option for rendering multi frames simultaneously and it instantly begins both processes.
Thanks for the help. Hopefully this doesn't crop up again.

The reason why Render Multiple Frames is making RAM preview to take so long to start is because you don't have enough memory for 8 cores.
So, turning it off of course helps, but you also loose the advantage of having a multi-core machine.
With 8 GB of RAM, you can turn it on, as long as you set "CPUs to leave for other applications" (in Preferences > Memory and multiprocessing) to 4 or 5, so AE uses 3-4 cores to render multiple frames.
That makes sense.
