My 2005 LLY sat for five days and when I started it up ( I let it warm up for about two minutes) there was no power steering or brakes.
I shut it down and started it again and they worked. First time this has happened. Is this a result of letting the truck sit, or is something else going bad? Thanks

Mine was the power steering pump. Only under the 36K warranty, IIRC.

If it was both power steering and brakes, it was your hydro-booster. Ive never seen one just stop like that though. they usually work, or not. my .02

I thought of that but the power brakes were not working either.
