Check engine light giving code PO087

Software has been updated, fuel pump in the tank has been replaced. This only happens when the temp is below freezing. Fuel heaters are turning on at the required temperature.
Anyone heard of this issue?? Thinking maybe the heaters are then cycling off??
Thanks

Based on the truck in your signature (2003).....you might get a quicker response in the appropriate forum.
