Reduced Engine Power

Hey guys has anyone ever experienced a reduced engine power warning with no other lights on the dash and what is probably causing it. The truck is a 14 f450 cab and chassis model. I had just had it to the dealer for this problem and the check engine light was on and the said there were two sensors going bad on the exhaust so they changed them out and sent me on my way. Well after driving the truck around all day and not one issue it had just decided to set the rep warning again but did not set off any lights. Anybody have any ideas? Thanks for the help guys!

Rep warning? Not sure what that is.

So as I understand it, you had two EGT sensors replaced due to check engine light and diagnosis from the dealer.

Now you have another warning indicator? Without scanning the computer you will have to take it back in.

Rep reduced engine power. And there are no dash indicator lights this time it just chimes at you and goes into reduced engine power and you can only go 5 to 10 mph. But if you shut the truck off and restart it runs fine for awhile

There should be some codes. I'd at least try autozone/napa if you don't have a scanner. See if they can pull the code.
