I'm not extremely familiar with the VSA, but I did help a few troubleshoot.
I would scan for codes. I like the Autophix ES710, YMMV.
Right off the bat...the on/off issue leads me straight to the battery.
I would check the date of the batt. then check/test the condition of it and/or the charging system.
Also check Batt & Ground connections. I like to remove, clean and antisieze grounds.
The last time I helped with a VSA issue, I remember ohming a lot of connectors, so I'd start at the battery first.
