Here's a workaround until you find the solution:

Once or twice in the past month I've posted a shellscript to toggle the
synaptics touchpad on and off. Connect that to a convenient hotkey via
your window manager, and every time it turns itself off, toggle it back
on.

This lets you continue working while you seek out the root cause.
