Kulp K8 with receiver - having issues with receiver freezing

[CharlieTheBeagle]

I have a Kulp K8 with a single receiver attached to it and one of the ports (seems to be which ever one has the most lights) freezes up or stops working after playing certain sequences.  I have tried remapping the ports in xlights and that is where I noticed the issues seem to only happen on the port with the most pixels.  Right now my port with the most pixels (12v) is 350 and I have power injection on my strings as well.  Have tested power injection and it doesnt seem to be the problem as I am not getting any flickering or anything but my pixels just stop working at all until I power cycle the receiver. 

The fix is just unplugging the receiver and plugging it back in and everything is just fine until it runs a sequence that freezes it again and then power cycling solves again.  What could be the problem?  Are there quirks with using receivers and kulps?

350 pixels without power injection is too many.
