Pentair variable speed pump 3.0 HP turning off randomly

Yes, it is on for 23 hours since that is what the pool company that installed pool told me to run it. It ran this schedule all season last year with no issues. Should I be running it less per day? I live in Midwest so pool is open from April until October. They informed me the less the pump turns on and off the longer it will last. I am on second pump since pool was installed in April 2012. Any advice is appreciated.

I'm trying to figure out the logic on this notion. Doesn't the pump turn on and off the same amount if it runs 23 hours/day or 12 hours/day? Perhaps time for a new pool company.
