You're saying it has happened across two engines, so fuel delivery seems to be the only common component.
Generally speaking, ok idle and sputtering/coughing at a non-idle speed is either ignition problems (timing, weak coil, funky plugs, seriously funky wires) or fuel delivery (weak pump, clogged filter, bad injectors).
Toyota pickups/4runners aren't notorious for fuel pump failures, so I didn't consider that a viable problem.

vacuum/air leaks usually fiddle with the idle and less problems as you go up in RPMs.
Another thing I just thought of.. O2 sensor will do this, too. I would think you'd get a Check Engine light, but could be a few reasons why it didn't come on.
