I had the same problem and did two things. 1. I made sure the fuel system was well bled A small amount of air trapped in the high pressure lines can create a lot of trouble with idle and stalling.
2. The second thing I did was add Howe's diesel fuel treatment to the fuel every time I fill up. The explanation I got was the fuel that was available when the M-430 was build had a high sulfur content which acted as a lubricant for the fuel injection system. The new (low sulfur) fuels don't provide the needed lubrication causing the governor to stick resulting in stalling. I'm not sure which (or both) fixed the problem, but I don't have the problem anymore. I hope this helps...
