Next time it stalls immediately do below to find out what's missing: Fuel or Spark

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

Thankyou for the reply. I have also had a lot of pinging under even a moderate load, might be related? Low fuel pressure? Removed and checked the ignition module, could not get it to fail even when warm and trying over 10 times.

Thanks again for the help, I am still wandering around in the dark. Coolant never over heats, guage is below half. I don't think this vehicle has a knock sensor. Think the EGR valve is still suspect? How do I check it?

How about timing chain? Maybe O2 sensor?

Step 1 Do a fuel pressure check if its within specs if okay do S2

Step 2 Get a vacuum pump to check the EGR valve or use its on intake manifold vacuum to open the EGR pintle-it shpuld drop 150rpm if its functioning

Is it possible the fuel pressure might only drop when it is hot? What does printle-it mean?

Also I notice the heater flaps seem to change when under a moderate load, a load less than I would expect them to change.
