Sounds like your fuel pump went out
I forgot to mention its a 6.6 duramax diesel. I can start it on starting fluid and it will run and idle good for a few miles and then go back into limp mode with a 2000rpm max. The p0087 shows low fuel rail pressure. Hoping its just the fuel rail pressure relief valve.
