I recall installing a Magnum ME-RC remote control (replaced a basic remote control) a few years back. That's the only system change. Perhaps the odd behavior is a result of this change?
From what I understand, the Magnum ME-RC only has an interface with the generator for the auto start function. Once the generator starts, it should have no influence. It is still not clear if you had this extended lag immediately after you installed the remote, or if it is a recent event.
Regardless of the generator maintenance history, which sounds like it's up to specs, the output of the generator needs to be assessed, IMO. A perfectly starting and running generator may not be producing proper voltage through each line output. Without data, everything is a guess.
So, a few direct questions to narrow down the issue.
Is this a new event?
What are the voltages produced by the generator on each line at the ATS at start up?
What are the voltages 30 sec. after start up?
What are the voltages at the ATS after the contacts switch?
If you are uncomfortable or unsure about checking AC voltages, let a pro do it.
If you can eliminate the generator as the problem, that leaves the ATS.
