Random no DP signal while connected via Thunderbolt

• XPS 15 7590 Windows 11 Pro
• Dock TD WD19TB
• Monitor 1 P2419H
• Monitor 2 P2319H

All drivers and firmware up to date.  Randomly receive a no DP signal detected on both monitors simultaneously when docked.  Monitor signal restored after waiting a few minutes.  This can happen while running any type of application, but seems to occur more when running a more intensive graphic application on either one of the monitors.  MB was replaced a couple of months ago and modified settings to auto selection input to off on both monitors.
