Short story. Just purchased the R51 (2011 diesel 3 Ltr V6), drove it one hour then stalled. Traveling at 90 kmh in left lane. Then stalled. Pulled over. Restart. Idles OK. I go to take off. Stalls again. Did it again. Put on truck and now at mechanics. No idea. No fault code. Maybe fuel leak or fuel related issue. Any ideas? Thanks brains trust.

Will it idle in drive with your foot on the brake? If it is dying as soon as it is put in gear I would suspect torque converter.

 

Otherwise, I would say fuel related. The mechanic should have the tools and knowledge to check the fuel pressure. If the fuel pressure is dropping off as rpm increase then I would suspect weak fuel pump, clogged fuel filter, etc.
