I have 94 Ford F350 Turbo Diesel that just dies while im driving I pop the clutch and starts back up but have to do this several times sometimes will run fne after a few times others I have to let it sit it seems even worse in the winter months never encountered this before and before I rip into it wanted to get some ideas from some that may have experinced something similiar its been rebuilt and has about 180,000 mile on it now

 

does your tach quit working during these periods and do you have any trouble codes theres been problems with the camshaft position sensor on them and welcome to diesel bombers you oughta post here so we can get to know you Diesel Bombers Initiation - Diesel Bombers

 

If its an early 94 its a mechanical motor, late 94 its a Powerstroke. If its an electronic motor, you need to have someone check it for codes. Being OBD1 you will need to find someone with the proper equipment. Either way I wonder if you lift pump is failing. Its a mechanical pump in the valley under the turbo on the powerstroke trucks. I don't recall the location on the turbo'd IDI motor.

 

Definitely need to know if it's an IDI or powerstroke? The early P/Strokes had issues with the camshaft positioning sensors on the front of the engine. Here is a TSB from ford regarding your symptoms as well.

ISSUE
On vehicles with a 7.3L direct injection (DI) turbo diesel engine, one or more of the following concerns may be present:

^ Rough Idle

^ Stalling

^ Hesitation/Stumble

^ Loss/Lack of Power

^ Poor Fuel Economy

^ Excessive Oil Consumption

These concerns may be caused by the injector cushion 0-rings deteriorating, resulting in a poor seal. This condition cannot be detected with conventional diagnostics (i.e. it will not produce diagnostic codes with either Super Star or New Generation Star Testers).
ACTION
Remove the injectors, check for deterioration of the cushion 0-ring. If necessary, replace the 0-ring with a new 0-ring which has a more robust design and should not deteriorate under severe conditions. Refer to the following Service Procedure for details.

SERVICE PROCEDURE
1. If no Diagnostic Trouble Codes (DTCs) are found and normal diagnostics do not lead to a solution, remove the injectors according to the DI Turbo Service Manual.

2. Check for wear or deterioration of the cushion 0-ring. If excessive wear is found, replace the 0-ring with a new blue 0-ring found in the 0-ring kit (F8TZ-9229-AA). Refer to the Instruction Sheet included in the kit.

NOTE IF ONE 0-RING IS REPLACED ALL 0-RINGS AND SEALS MUST BE REPLACED. IF ONE INJECTOR SEAL IS SERVICED ALL THE INJECTOR 0-RINGS AND SEALS MUST BE SERVICED.

The 0-ring Kit includes the following:
^ One (1) upper Backup Ring

^ One (1) upper Cushion Ring

^ One (1) upper Injector Seal

^ One (1) Seal

^ One (1) Lower Injector Seal

^ One (1) Injector Gasket

^ One (1) Instruction Sheet

Sound like the crank sensor very common buddy of mine replaces about 1 if not 2 on his truck a year. Not that expensive and takes about 15 minutes to change with a 10mm 1/4 inch drive deep socket and a small screwdriver if I remember correctly
