That can be problematic so it's good you noticed it. The reason I'm saying your wires are fine is because you say it runs perfectly fine at times, other than the fact that it stalls after 5 seconds. That wouldn't be possible with wires in a bad order, or an unplugged wire, etc. Also, our engines are perfectly capable of running without one cylinder, so you're looking for something that affects at least two of them, intermittently.

However, as a side note, I would replace your Taylor wires with the factory NGKs found here as soon as possible.
