Resurrecting an extinct thread here I know but I'm curious if you ever got to the bottom of this? My Patrol has intermittently shown similar symptoms in very similar circumstances.
Generally happens when starting stationary at a roundabout, then giving it a bit of pedal to sneak in before the next car comes round... hits about 2500rpm then the whole car jerks and accelerator goes unresponsive for a couple of seconds. I take my foot of and gently ease back on and everything is fine again. I haven't ever had it cut out completely afterward. Anyway, after not happening for a couple of months, I got it again today. My scan tool gave me P0087 which apparently means low fuel rail pressure. I can understand the effect, just not the cause. I guess I'll quiz the mechanic when I take it in for a service.
