Well, this is kinda reaching, but the UBEC could be a culprit. After some time loading the UBEC, it will get a little warmer and might change some if its characteristics. Switcher regulators can be "fussy" at times if not designed exactly right. Try adding a capacitor to the power and ground leads of the unused Rx output. This will at least clean up some of the possibly noisy power going to the Rx. If the power going to the Rx is not clean DC, the signal coming out might not be pretty either and the ESC might get confused. Adding a cap is always a good idea IMO; not only does it help clean up the DC, it also provides a little more current capacity so the UBEC doesn't have to work so hard to provide fluctuating current demands. I usually use 1,000uF and 10v to 16v.

To see if this would even help, try using an Rx pack first.
