F) truck would not start, I tried cranking several times and still would not start. I noticed I could not hear fuel pump working. Two days later (about the same temp. outside) I tried again and could hear fuel pump and truck started fine. It drove fine ,but then a half hour later after shut off, again no pump noise/no start. The next day worked fine again. I ran out of gas a week earlier and re-started several times after initially running out of fuel.

Just a maybe from similar cold country. 17F as I write and expected near 10F overnite.
