COld weather fuel goes missing

when its -10 or -20F below after it sits for days for some reason i start the IDI and it dies after a few seconds, runs outa fuel... i have to reprime the injector lines to get it started again, any idea what this could be?

doesnt happen in 10 20f degrees.. need to know where i should be looking, put a line kit on it with new caps and injectors this summer.. its a 85 and i bypassed the water seperator also.

You have o-rings, olives or return line fittings shrinking in the extreme cold and causing air intrusion.
