When mine did that it was the fuel shut-off solenoid relay, located on firewall at rear of engine.
Purge the air out of the fuel lines at the filters and pump. Some times it's easier to crack open the bolt on top of the injectors one at a time to remove the air bubles traped between the pump and injectors. You might want to check the ohm resistance on fuel heater. Using a ohm meter connect to the two wires connected to the heater, the ohm reading at 40 degrees will be 1 ohm. and at 80 degrees it will be 1,000 ohms. If not to this scale replace the fuel heater. If no power to heater look at the relay next to the brake master cylinder. Hope this will help you.
