The wheels well and truly came off in the second half as Ely City lost their second league game in three this campaign.
After a goalless first half, Stowmarket struck four times after the break against nine-man Robins, who also had manager Brady Stone sent off.
The Robins will look to bounce back when they host Diss in the Thurlow Nunn First Division on Saturday.
