Cubase 8 Elements Audio Drop out but only on one track

Hi There,

Im currently working on multiple tracks going through the mixing stages and on one track i continue to get audio drop outs for about 3 seconds at a time at least 4 to 5 times throughout the track. Each time it is at different points. On other tracks i do not have this issue and to the best of my knowledge im using the same setup on the other tracks.

I have checked for latency issues and im green across the board and cpu usage is sitting at 50% so again no issue.

I thought it might be something to do with project setup but cannot see any issues.

Any ideas would be appreciated.
