i have a full size 95 chevy diesel and am currently living in el salvador.
this full size model is very rare her and i am havingproblems finding a decent mechanic or figuring out the problem on my own.
It's stalling out on me a lot, usually when its hot. it will almost always start back up but then stall again. We've changed the fuel fflter and checked the pump and supposedly replaced the diaphragm indside the pump.

any ideas on what to check next??

I have two 95 gmc pickups with diesels. I have had the same problem with both of them. On the driver's side of the injection pump there is a black box that is about 2"x4" with a plug going in the back.
It is called the injection pump driver module. It's probably your problem. You have to pull the intake manifold off and be careful when installing the new one. You can only torque the 4 mounting screw to
25 ft/lbs. THe plastic is fragile and over torquing will crack it.

I had this same problem with my truck, its a 94 6.5 turbo the black box that sit on your pump mite be the probelm. I had it changed and that fixed it. It cost me 250 dollars for the part and i had a guy i know that work on these trucks fix it for me, I payed him a 100 dollars. But he did this at his work place. he said they come preset from the factory but some times are not right so you have to put it on a machine to set it.

The "black box" referrenced is the PMD Pump Mounted Driver and is the most common part to fail on the GM 6.5's, heat is their enemy and mounted in the hot engine valley is no place for it's sensitive electronics.
To replace the PMD where it is- you need to do quite a bit of work- like removing the intake manifold and turning the injection pump to access the lower bolts, and then need a Tech2 tool ($4000+) to reset the "TDC offset learn". Then if you do put the new PMD there again it is destine to fail again from the heat.
However don't despair- there is a much easier way to fix and keep the PMD cool too, it is the PDC Pump Driver Coolerclick here and then click on PDC. With the PDC you simply unplug the old PMD and plug in a remote harness to reach the new PMD you mount away from the hot engine. 10-minute job using basic tools to mount the unit on the firewall. NO setting and NO adjustments required. This is the way to go...
