Tracks play then stop mid track and freeze...

Sorry to hear that, but I'll need some more information to help you further...

- What controller is it?

- What version firmware is installed on the controller?

- What version of rekordbox are you using?

- What is the operating system you're using?

- What driver version is installed for that controller?

- What is the bit depth / sample rate of tha WAV file?

- Did you recently import that WAV or was it analysed with an earlier version of rekordbox?

- Have you ever moved or renamed that particular file?

- Does it happen with more than just that one song?

XDJ-RX1 

Rekordbox 5.3

Bit depth is 16

All of my tracks haven't been changed in any way. 

Its happening to more the one track.

If I restart the controller the track will play through.

Additionally, if this is happening with an export device (RX in stand-alone mode) and not while controlling rekordbox, what is the make / model of the USB device you're using, and what is the filesystem it's formatted to (eg. FAT32, HFS+)?
