I found the culprit, it was a broken abs housing on a hub I had previously installed. I had replaced a hub, due to a supposed bad rear abs sensor. The bad abs sensor turned out to be a faulty abs module. The new hub I installed had a taller abs housing than the OEM version. The taller housing meant that it protruded farther back than the OEM unit. Apparently it cracked perhaps rubbing up against the strut mount, but needless to say the broken housing meant that I was losing continuity to the abs sensor.
When I took it all apart the sensor seemed fine and I was able to glue the housing back on. Not sure how long it will last me, but it is interesting to note the change in housing height and/or depth when looking for a replacement. Since repairing the housing I haven't had the problem come back at all.
Other people might want to check out their sensors or housing moving forward with similar issues.
