Hi cpt_ri_F5 , 

Can you bypass bigip and try to download it directly from server ? To make sure that bigip is point of interrupt your download. 

Pcap may give us some insights , you may find TCP-Window-FULL and TCP-Zero-Window. 
you may need to increase bigip buffer of window scale from bigip. 

But test first from server itself directly without bigip in path.
