Surprised you didn't get any warning lights.. I'd think low trans fluid may keep it to a certain gear, but would also think it would warn you

Also I am seeing these posts under class C forum. Not sure if you want to post in the class A forum instead? A moderator could move the posts to class a or the owners forum if they review these too

If not the fuel filters, then the air filters, On gasoline powered cars I have had that happen when the air filter clogged.

In either case, Time for a filter change. Might as well do 'em all.

Surprised no dash lights/alarms also.........have/ask the Mods to move this for you to the proper engine section......what kind of engine do you run? Cat or Cummins......
Guessing Kitty-kat?
And one more thing, Welcome here to the forum!

Engine Warning light on Dash

Hey guys thanks for all the input. I am getting and engine warning light on the dash. This happened once before when I was stuck in traffic on the 405 in LA. I pull over parked for a while and restarted it and it ran fine. All other times we've driven it it's been ok. Help.

Tony, you did not answer any of the above questions , What engine, and have you changed the fuel filters lately? The filters are the first place to start and the cheapest thing to try, if they don't work, you are going to have to take it to a shop that can extract the codes that are up and correct the problem........

my experience with limp mode is if your lucky you might just be able to get out of an intersection.

With my Duramax, when it goes into limp mode, I can eventually get up to highway speed. The limiting factor is the RPM which will not go above 2,000. I have gone into limp mode a few times over the 150,000 miles driven so far, for various reasons, but usually it is because of a dirty fuel filter. A dirty mass airflow sensor can put you into limp mode, also.
