I had a simular problem with my truck last winter. It turned out that some diesel fuel suppliers (to save . 02c per gallon?)did not climatize the fuel for use below 15 degrees F, causing wax to crystallize in the fuel. The wax blocked the fuel screen in the tank stopping fuel flow. What I did was add FPPF "Melt Down" to the tank as directed, and warm the tank carefully. I removed the fill cap, disconnected the fuel supply line at the lift pump and used compressed air to clear the line and screen. The fuel system had to be purged of air. After that, the truck started and has ran fine ever since. This winter I have been using Power Service "Diesel Fuel Supplement" w/o any problems. IMHO, I would recommend using a fuel additive each time you fuel up as well, and not to trust any fuel station to have added it to their ground tank for you.
