SOURCE: truck just shuts off
I own the same 3500 GMC 6.5 diesel truck with the same problem. We replaced the brain under the upper turbo hood and it fixed it pronto. No more shutoffs

Yo man, i have the same bakkie more or less same problem.Lights came on as i was driving on the highway and it just died...pre ecnition...Starts then dies again...bla bla bla.List goes on!
Start by replacing the Petrol pump relay!!!+- R400 i think.
Its next to your right foot ,next to gas pedal.Behind that cover.A small black box!
don't buy it from a dealer!

I realise you have probably solved this problem by now so sorry for the late news mate . Had a similar prob and it turned out to be an alternator malfunction . I replace the brushes and off she went . These things send voltage from the alt . to a fuel pump relay or whatever so the pump wont run if the eng isn't (or the alt isn't outputting any voltage.) . Hope you already had it sorted . But I hope this helps if not . Cheers Simon .

if ur engine is a c14nz its probabbly ur ignition module, its the part right behind your ignition coil, when they get too hot they stop sending the electricity needed and the car just dies while ur driving it, after a few minutes it cools off and then u can continue yout trip...
must be replaced to fix the problem
if ur engine is not a c14nz, let me kknow wich one is by giving me your vin number and also engine number so i can give u a hand
let me know
