Thanks for those settings MM, I'll change them tomorrow and see how it runs. I checked the bearings near each wheel, and in the center diff, but haven't gotten a chance to check the bearings in the front and rear differentials yet, so I'll do that tomorrow as well. I would think that if the solder connections weren't that good, it would cut out power as well, but it can't hurt to check them.
Thanks again for the help. Hopefully I'll report back with good news.
