Have same problem with Thanos driven 4 actuator setup ran by SRS.
SRS can be set up to record the raw telemetry it receives, and it drops out (meaning: all telemetry variables are set to 0) a few times every minute. I have found out that it gets worse when running CPU intensive takes inside MSFS. If I open Navigraph in-game panel, telemetry will drop for several seconds and cut in and out. It I quickly zoom in and out on the G1000 map I can force a telemetry loss. So this looks like some CPU prioritizing issue.
Hope others with the same issue can pipe in so maybe this issue can get some traction…
