codes 11,21,43, and 55 show up my guess is the oxygen sensor

Your codes "11" & "43" are your key references. If the ignition reference signal and your ignition control fail, the engine cannot run properly.
if your oxygen sensor fails, the engine may run rough or lose a bit of power, but won't cut out. Its sole purpose is for fuel control.
Check for primary ignition failures, such as ignition module in the distributor and the ignition coil. When either are in use for a few minutes, heat will be present, and heat expands. When there is physical expansion, there can be physical movement and circuits can change resistance and or open / short conditions can exist.
Good Luck

Sounds like an ignition\heat problem causing a missfire that throws off the O2 sensor reading.
I'd start with sparkplugs.

the module is weak in your distributor and needs replaced. Don't forget to put the grease they send you in the little packet between the module and the distributor when you replace the module, otherwise it will ground to your distributor base and won't run right or not run and all

you should take it to your local Autozone and have them test it. and they can recommend what to do next.
