i paralleled my lipos with no issue but they are 11.1v opposed to 18v
i think the voltage gremlin spike is at work here.
now any config of any type of cell will run randomly then conk out, before it would run until almost flat.

I had a similar problem with my v2. It would run for a while and would cut out when I would try to make a top speed pass. Sometimes it would cut off completely and coast to a stop, and other times it would stutter on top... almost like the Novak lvc cut off does when your batteries get low. One time when it shut off completely I went to unplug the battery and as soon as I touched the power wires it started going through the initial beeps like I had just turned the switch on. It ended up being a bad connection in the positive 6.5 bullet connector, not the solder joint but the actual connector. I cleaned it up with a small wire brush and tightened the male bullet with a small screwdriver and all has been well since.
Here is a pic of the connector:
