By 10 minutes you're down to 280ish - and fading FAST.
If your FTP is really what you claim, you can hold that power for an hour. If you can't hold that power for an hour, your FTP ain't what you claim.
It's really that simple.
It doesn't ****ing matter what you can do for shorter intervals, even if you fudge the numbers by 25W. Because your anaerobic capacity is masking your aerobic numbers for those shorter intervals - and that's why you're fading FAST by 7-8 minutes into your intervals.
And if you can't talk when you're doing a "moderate" pace, you're lying to yourself about the pace being "moderate".
I'd love to see you post a file from a trainer session where you held even 250W steady for 60 minutes. 250W plus or minus 10W for 60 minutes with absolutely no stops. If your FTP is really where you say it is, you'll be able to do that no problem.
