M1008 cold weather issue

[1984CUCV]

I shipped my m1008 from florida to maine in June and had no problem starting the truck in maine until 3 days ago. I left the truck outside and tried to start it in the morning with the outside temp about 35 degrees. The truck started fine and ran for a few minutes but when i started down the road the truck stalled and would not start. I thought it might be a plugged fuel filter so I changed it and the truck started and went down the road fine all day(by the time I got the new fuel filter the temp was about 50 degrees out). Well the same thing happened this morning (stared fine, but stalled and would not start once I got 100 yards down the road). Once the outside temp got up to about 50 degrees the truck started fine and went down the road with no issues.

Any ideas on what could cause this?? Thanks.

BTW the truck is 100 percent stock with no modifications.

Unrelated to your stalling problems, these threads are for the starter relay modification:

Your truck is old. I had air getting in my fuel lines from old dried out cracked hoses on the fuel tank lines and air from the filter mount knob on top. For the colder weather I installed a manual toggle switch to control the glow plugs on/off time. Also a 1000 watt block heater Hope this helps.

Have you ever cleaned the inside of your fuel tank since owning the truck? Have you replaced the fuel lines from the tank and the one going to the IP. They are at least 25-years old and made of rubber. Did you cut open the first fuel filter and inspect for water or perhaps "black specs?"

Also have a shop that can do it check, and if necessary, readjust your idle speeds. These trucks have two idle speeds: a fast idle speed when the engine is getting warmed up and a slow idle speed for everything else. You can check and adjust these speeds yourself, but it requires a special tool (namely a diesel timing meter) to do so.
