Hi,
Chances are shorting the wire isn't causing this. If the battery was failing, I would think it is related to the alternator but since it starts right back up, it appears to be charging.
Based on the description, it sounds like an engine vacuum leak. Have you checked for leaks? If not, let's start with that.
Here is a link that explains how to check and repair an engine vacuum leak:

Let me know what you find or if you have other questions.
Take care,
Joe
