Electrical gremlin is driving me crazy !!

[OURGMH]

I have a vt wagon that keeps stalling after a bit of driving, it just dies, the dash all goes off but the car always starts right up again. at about 1500 rpm 80kmh it acts up a bit as well. every time i think i have it sorted it behaves for a few weeks and then acts up again. The car has had new keys programmed, new crank sensor, new alternator, alternator wiring, starter wiring, battery leads, battery, fault sensor module, relays put in for the ss spotlights wired into the parkers ( vx ss body kit ) all of the things i have done were faults in there own rights but the problem is still there, car has a brand new auto in it as well.. any ideas its driving me insane !!! Thanks for any help... maybe its not electrical and something else ?? its been to holden twice and 2 other mechanics plus an auto elec... ohh its a v6
