I just got a 99 Suburban with "The Famous" 6.5 diesel.
It stalled everytime after few kms running.
new pmd and relocated. replaced ops and lp. what else?
I'll check fuel line for air sucking in.
if anyone has good idea to check, welcome!!

 

IP itself.... dad is currently replacing his..

 

I just checked and the problem was no LP operation when engine is running. I just replaced the OPS few days ago. What I'm guessing is a broken wire between the OPS and the ECM. If someone knows where I can get a wire diagram or what coloured wire has to be checked, Pls let me know.

 

Post this in the GM thread 6.5 and you'll get more responses
