Is it possible?

I discovered recently that a Walthers E7 diesel that had been running without issue suddenly was shorting out a power district. Close inspection showed no obvious problem in either of the 3-axle trucks. Instead of following the usual procedure of checking for internal wiring problems, I decided for no particular reason to try reprogramming the loco.  Presto changeo, the loco once again runs without throwing a short.  I have to wonder whether I'm dealing with some type of intermittent failure in the decoder. Any thoughts?


Which decoder?
Walthers has uses Tsunami, QSI and Loksound as decoder source.
