Yes, if the condenser is not receiving adequate airflow, pressures will rise, and the system will shut down... again, this will occur at around 400psi. Poor cooling will be noted well prior to the high side reaching 400psi.
If you spray water on the condenser with a garden hose (through the area under the nose where the cooling stack receives its air), while the system is running, this will allow the condenser to shed all the heat it needs to, so you can see if the system is still cycling.
