The switch contacts are probably dirty. They can be cleaned if you can remove the switches without disassembling the door. Not familiar enough with the Suburban to know how easily this can be done.

Having the same problem with my 2001 Merc Cougar, When does it black out? While reving or randomly? Mine is while heavy accelerating. Could be over voltage at the charging system (alternator or regulator) or internal in the cluster. Get the alternator and batt tested first, ask for a load test, then try the cluster next.

DTC C0561 72: System Disabled Information Stored Alive Counter Incorrect
DTC C0561 74: System Disabled Information Value of Signal Protection Calculation Incorrect
The electronic brake control module (EBCM) receives serial data messages from the body control module (BCM), engine control module (ECM), instrument panel cluster (IPC), and the transmission control module (TCM) which are needed to perform antilock brake system (ABS), vehicle stability enhancement system (VSES), or traction control system (TCS) functions.
Conditions for Running the DTC
Ignition voltage is greater than 10 volts.
Conditions for Setting the DTC
The EBCM receives an invalid serial data message from another module.
Action Taken When the DTC Sets
The EBCM disables the traction control system (TCS)/ vehicle stability enhancement system (VSES).
A DIC message and/or a warning indicator may be displayed.
The condition for the DTC is no longer present.
The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
This DTC indicates that there are no problems in the EBCM. The BCM, ECM, IPC and the TCM should be checked for a possible fault.
