what do you think?
 

I have posted this problem before,my 2000 accord v6 runs great in the
city,it will tach up to 5000k when I need to pass.Once I get on the highway
and pass someone at or above 70mph the fuel shuts off,but the car ill still
be running.After this happens I can't accelerate past 3500 rpm on the
tach,I get fuel cut off regardless of city or highway driving.Next day all
is normal until I break the 70mph,car runs like crap.So is the fuel
pressure regulator or fuel pump itself, or some sensor? Help anyone, or
I'll bite the bullet and head to the dealer.TIA.
