sACN issues

I am using a NX wing with a windows 10 PC and a Doug Fleenor PRE10ETHER-A (lockout mode) sending sACN to (3) Chauvet AN2 units feeding 3 universe of DMX. I randomly experience the sACN from the console stop for approx. 15 seconds and will fall over to the settings on the wall controller. has any one experienced this or know what may be causing it? i have not found any errors in the info window of Oynx or windows event viewer.
