Hi,
After this happens, does the engine idle smoothly? I ask because my first thought is an engine vacuum leak. Have you checked for any?
If not, start with this. Here is a link that explains how to find and repair one:

Let me know what you find. Also, let me know if when this happens the engine keeps pulling the vehicle as if it isn't releasing from the transmission.
Take care.
Joe
