Dolphin Dies After First Play!

I have recently downloaded Dolphin 4.0 x64 for my computer. I am emulating Fire Emblem: Path of Radiance for the Gamecube. The program itself opens fine, and when I start the game, it works great, usually running between 30 and 60 FPS. Unfortunately, the next time I try to play, the game tanks to 0 FPS and Dolphin crashes. EVERY TIME. Words can not express how frustrating this is. I have installed everything required for Dolphin to run (seriously, everything. I've been searching for hours. @.@) Before anyone starts talking about how my graphics card is not recommended, I believe that my graphics card is not the issue, seeing as the game runs fine the first time. Do any of you know what could be causing this?
My specs are as follows:
CPU: Intel i5-3230M (2.50GHz)
GPU: Intel HD 4000 (lame, I know)
RAM (4GB)
