911 need some help 2010 F550 problem

Hello everyone, my brother in-law has a 2010 ford f550 with a 6.4 and about 50k miles on it. Well he is out in the snow and the tuck just shutoff on him and almost every light on the dash lit up. The truck does restart and idles but when he puts it in drive it instantly shuts off. Any ideas?

I am going search for answers, but since he is stuck alongside the road I wanted to post this up.

I appreciate the help.

Thank you,

Paul
