Fail installing updates event log

Did you check the Config Mgr logs? 
wuahandler.log
updatesdeployment.log

rebootcoordinator.log

We typically check those 3 in CMTrace (merged view) and can find errors with the updates installing. Sometimes they are general, non-specific errors that aren't helpful, but other times, it will tell you error "time-out exceeded" etc. 

You may need to run a PS script against your Software Updates Catalog to set the max run time. By default it should be 60mins but we've caught a bunch that were reset to 5mins. We have a script that we run now to increase it to 90 or 120mins for CU's etc. (if required).

I would check in those places and then hit the Google machine for the update run time change.
