I have a bit of a puzzling situation I would like some advice on.
I have been running a warp 9 and zilla 1klv for about 3 years/15k miles.
I replaced the original set of brushes about 4 months ago with a set of National T300's and I seated them for a total of roughly 1.5hrs at 12v
(edit: I measured resistance after blowing out the carbon as described in the Netgain manual and I was happy, I don't think this is a ground issue)
Logged about 400 miles since they were installed.
Last time I used the truck I had a situation were I lost power and steadily could only push about 15kw, then 10, then 5 and all the way down to crawling not able to increase power above 1kw. A quick key reset fixed the issue and then it happend twice more (panicking and calling for a ride on my morning commute

)
I checked the zilla for codes and nothing was set, only "1111" No Error/Unknown state codes.
I checked the brushes and they are seated nicely and very smooth.
I have not been able to reproduce the situation but I was wondering if anyone else has experienced similar and has insight ?
Thanks
Dave
