it can be a fuel problem could be the regulator or the fuel filter, if its not getting enough fuel it will turn down the air flow, can also be a vacume leak if its broken or leaking, this would mean its getting more air than it needs.

Never, ever use starting fluid in your diesel.

Taken from the Owners Manual - Diesel Supplement:

Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system (see Air
Cleaner Decal). Such fluid could cause immediate explosive damage to
the engine and possible personal injury.
Do not add gasoline, gasohol or alcohol to diesel fuel. This practice
creates a serious fire hazard and causes engine performance problems.
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to Seating
and safety restraints chapter in the owner guide.

Bad Injectors most likely. I have a 2006 f-350 and was having the same problem. I ended up changing the fuel pump and 4 injectors.

sounds like your injector pump is weak. next time it dies and wont start try ice on the pump, if this helps you have a bad pump

fuel pumb leak coz it is normaly conected with the engine by gears

Yes, You Can do it. Normally Glow plugs located near the Injectors. But you have to use Rust off Liquid.(WD 40) Because, When you try to remove glow plug it can broken.If glow plug broken you have to dismental your engine Head.

Then your problem is in the glow plugs or the glow plug timer.do you hear and see your normal wait to start and hear the clicking noise from the motor.Realy switch in back of motor..
