About halfway through a 15 mile commute I came to a stop at a light and the truck died. I put it in park and hit the start button and it cranked, but did not start. Hit it a second time and after a long crank it started, but was in limp mode for the rest of the commute. After sitting a few hours it still had a long crank and stuck in limp mode. The next day it started right up and no limp mode.

Pulled codes and it came up with multiple misfires and P0191 "Fuel rail pressure sensor range/performance" Check engine light never came on.

I have have put 200 or so miles on it since without issue.

Bad gas? fuel pump? Thoughts?

Potentially the fuel rail pressure sensor? Had a similar fault on my Discovery.. we replaced everything, fuel pumps, filters etc only to find it was just the fuel pressure sensor itself…the reason it goes into limp home mode is that the car thinks it is running lean and as such shuts down to protect the engine from serious damage..
