Could be one of three easy things:
1.) The refill on fuel disturbed crap in the tank and it plugged the pickup.
2.) You were so low already that the pickup allowed air and or bubbles into the line, so you may have to bleed the system of air/bubbles. (look in your owners manual, or google/duckduckgo it).
3.) Visually check your filters also for crap/air
