Roland TD17 freeze

Had a gig last night, first time with the TD17, combined with VH10 hats, some very cheap drumpads and cymbals and nice kickport.
It was awesome, the sound in the mix was very good and distinguished, lovely punch of the snare and kick of the kick.

But, starting the third set, ironically with Queens Don’t stop me now, it counted off on the hats and we were off full steam into the song - that’s every other bandmember but me. Soundmodule was completely silent and unresponsive… Sheer panic and some faces from the band. Singer decided to quit it and restart the song, talking his way thru the gap (he did great!).

I checked the cable-attachment on the bottom, all solidly in place. Turned the module off and on and bam! into business again. Not a single issue furthermore.
Anyway ever had this happen with the TD17 specifically or Roland in general?
