Glitches in audio

I own a DDJ 1000 (firmware 1.04) and everytime i use it i get glitches in the audio.

Strangely they occur around 1 hour for the first time. I tried reinstalling drivers and software, changing latency to 512, without succes... I use an i5 2,5 Ghz 8Gb laptop that runs on Windows 10 proffessional. When i play an all night gig, it happens about 4 to 5 times, wich is really annoying and should not happen with a Pioneer product... So frustrated i cancelled several gigs just because of it.... Anybody ????  HELP !!!!!!
