My friends 2000 CTD auto will stall at very low throttle (from stops) only after driving for several hours. Dies just off idle. No check engine light, no loss of power, no dead pedal. Only mod is a Edge EZ & A full DDT. has 70k miles Lift & inj. pumps have been replaced approx. 5k miles ago. Idles at normal speed. Again, the only time it shows up is on acceleration from a full stop. Thanks in advance
