I wonder if they are holding the load? You were with Panther and you get those every so often, but certainly not a steady diet of them.
That was my single largest beef with fedup. Many loads i picked up on Monday were booked Thursday or Friday, and instead of dispatching me so I could relax a bit over the weekend, they held it (and me hanging) until about 60 minutes before pickup. Actually it wasn't just over the weekend, it happened any day of the week.
