I have a 2004 f350 powerstroke. When I accelerate hard my gauges & radio shut off & comes back on. The truck stays running. It's only the instrument gauges & radio. Does anyone know what this could be? Thanks

I did check the running voltage & had the alternator & batteries checked & everything is good.

That’s the same thing that happened with my truck and it ended up being my alternator.

Having an alternator "checked" doesn't mean it's good, just means it passed. Bad bearings and/or overheating will shut the alternator down.
You need to check the voltage while driving just like when it happens.

Listen to 6Riders. When you replace the alternator spend a few extra bucks and get a higher amperage unit from a reputable company. Your FICM and batteries will thank you for taking care of them.

I have same prob. I've got an aftermarket high output alternator, SCT shows 13.5V steady. If your windows don't work when this happens it's a problem with your cluster. The battery keep alive circuit or whatever and probably has a broken/cracked solder contact. I'm positive that's the problem with mine because I also can't "save" a time change after I turn the truck off. My clock on the radio is an hour behind... I took mine apart a while back and couldn't see anything wrong even with super close inspection- naked eye no magnification (which is truly needed, I am an aviation electrician), so I put it back together and it worked for a month daily driving no issues, then came back to doing it everyday.
I'm waiting until next time I take two weeks off work to tackle it again and send it off to circuitboardmedics. They have an advertised 1 week turnaround. They seem like good dudes and helped me trouble shoot a speedo issue on a 7.3l over the phone for free.

That's the exact thing that my 2004 does. I'm going to get a 250 amp alternator from hi amp specialists. Thank you for the info. Semper Fi

Any luck with the alternator?
I went ahead and wasted some money by having a shop work on my cluster to no avail. Then I exchanged the cluster with circuitboardmedics.com like I told you I was going to lol. I ordered a refurbished one with better parts and led backlights for $329. Got it in two days fixed my truck in half a beer.
