Hey folks. I found this while suffering the same issue and I (think) I might have something that might help.
I have 2 WiFi networks in my office (2.4Ghz and 5Ghz). My Mac has the logon password for both in keychain. Throughout the day, my Mac would randomly switch between the 2 networks.
I found that my trackpad would constantly drop shortly after connecting to the 2.4Ghz network, to the point where I can re-create the problem at will. Spoke with Apple support and they told me that WiFi can interfere with bluetooth as it's on a similar frequency.
Forcing connection to the 5Ghz WiFi network and removing the 2.4Ghz network has made the problem go away for me. My guess is that there might be a clash between the 2.4Ghz WiFi network and the bluetooth frequency (which is also 2.4Ghz).
I've a bluetooth Apple keyboard that never causes me any problems, just the trackpad.
Hope this helps someone.
