Windows Server 2008 R2 - Scheduled Task randomly executes script

i having issue windows scheduled task executes vbs script.  i have same script running same configuration on server without issue. task shows starts , completes without issue the vbs script not being executed. have other windows scheduled tasks configured on server issues running without issues.  i have noticed when delete task , re-create run first time without issue, beyond random.  hoping has answer bizarre behavior.   below xml configured task:

<?xml version="1.0" encoding="utf-16"?>
<task version="1.3" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
