Ah ok, sorry, a little misunderstanding :-)

Could be, but should not happen. The GPS should work also without assisted GPS for a while.

I'm not using intervals :-)
I used the word 'interval' to point out that the issue occurs with a frequency/interval of 20 minutes.
Could this issue be caused by assisted GPS not working due to lost phone signal and/or internet connection?
The last training shows a different pattern, only in the second part of the training the issue occurs: http://www.gps-sport.net/trainings/mountainbiking_1666316
Strange that the 'GPS signal lost' warning sounds every 20 minutes (interval is precisely 20 min)!?
See for example these training sessions, GPS signal spikes each 20 minutes:
