Sorry to hear that, but it kind of sounds like the power supply is going.
If it is repeatable every morning at power on, talk to your dealer about having a tech put one in for a few days for troubleshooting and see if it goes away. If it does not, then they can put the old one back in and move on to something else. If it goes away, then keep running and pay for the power supply.
Yes, you will have to pay to have the tech put the p-supply in, but at least you will not have to pay for the part if it doesn't fix the problem. Also, you will get a 90 day warranty if it is the problem.
Best to do it now while you can "schedule" the down time as opposed to waiting for several days for a tech to show up when you are up against a deadline.
Hope this helps and good luck!
