I think I have same issue:
XPS 9370. Self-installed Ubuntu 18.04. Not sure which wifi adapter (how can I tell?).
Bluetooth AND Wifi dissappear after waking from sleep.
Note: I have configured "deep" sleep, as by default it was not conserving much power at all.
Sorry, I do not mean to add noise to this issue, I just wanted to say it (seems to) affect others too.
