86 D21 6 cyl 4wd engine stops running

[infotraker]

Running good then engine stopped . Will start and idle for few secs. then stops. Will run very badly if you constantly move the gas pedal. Plugs, rotor,cap, coil good. Changed fuel filter and fuel pump, no change. Checked computer and it says ecu input sig. beyond the normal range. Could this be a ox sensor problem ? Any other ideas ?

I also have a 86 D21 but it's a 2wd with 638,250 miles. Mine did this at about 250,000 and I changed the catalytic converter and solved the issue.
