GPS died?

[Snicker]

Please provide a log of the GPS. How was the reception before the module has died?

I don't know where I can find any logs? The reception was excellent. I had 14 satellites in view on ext. antenna mounted on the rooftop. And very fast fix position. And no GPS errors.
Now it gives me the GPS error a minute after boot. "No valid 1PPS pulse" no matter if the ext. antenna is connected or not. No green light next to the GPS chip.
