I have the same intermittent issue except it appears to be at the beater bar end.....(an old beater bar / floor unit works just fine with this wand and canister)
I have taken apart the bottom section to inspect the wiring and connectors and don't see anything burnt. I sandpapered the male connectors just for good measure.

Would replacement of the lower wiring harness (~$40) be the best bet?? I think it has the power to the beater bar and light plus some dirt sensor functionality (a couple small wires and circuit boards are wired in)??
Other suggestions (besides just use the old beater bar unit!) :-)   ?

Thank you.
