I assume there's a problem with alternator. Check the grounding to engine, check continuity of a positive wire between alternator and battery. the energizing voltage should be checked as well. Might be the bad connection between battery and vehicle body grounding. Diesel cars are sensitive even in a little loss of connection and rust in the connection points.
Try replacing your battery. It takes a lot of power to start your motor but only a little to run lights etc. When you get a boost from another car your using the other cars power to start yours.
Thats definatly a crankshaft positioning sensor the reason why it dies after 20 minutes is heat expand and cold retracts kinda the same with the senor as it heats up it loses contact it is located back side of the head on the upper right about an inch below the valve cover
My suggestion is to provide an auxillary fuel source, for diagniostic purposes.
Does the vehicle run porperly when running down the road? if so, fuel flow is not your issue.
What is the normal ambient temprature where you use the vehicle, especially during the dying event?
Has the vehicle heat soaked (which is normal) prior to the issue? Heat soak happens when you turn off the vehicle, no more cooling, temps spike, sometimes causing problems.
During the dying event, does anything that you do help? give throttle, etc?
well the running issue could be the fuel pump it could be over heating but it also sounds like the crank position sensor as far as the heating issue it is normal to go up to half way but if it is over heating take the cap off once its warm you should see the fluid cerculate if not your radiater could be clogged
does ur car heat up? if not please check your ground coz it may be rusted. What I suppose it is: your fuel pump. they die slow. Immediately it dies, hit the gas tank with a 2x4 and if your ground is good, it may start or you'll hear the pump turn on immediately you put it on ign.
