    I would start with a fuel gauge. Connect it to the rail and tape it to the windshield so you can read it while driving up a hill where this happens.

    Agreed, sounds like a fuel issue. Start there.

    Does the transmission downshift at part throttle? if not look to see if the trans cable is disconnected at the throttle body.

    Are you low on gas when that happens? I've learned to never have less than 1/4 tank in my car.

    Did you wire the plugs correctly? Might want to recheck.
