I had the same problem on a Rover. There was a leak in inlet manifold that was caussing the problem.
To verify, spray some sealant to temporarily seal the inlet manifold .and the eratic idling should disappear for some time.
If it does, you know there is leak in inlet manifold which you can take of and refit with a new gasket.

Make sure your pressure switch is set correctly. Check your pressure gauge and make sure it is functioning correctly. Also,seems sometimes if there is any time when there isn't the adequate amount of power demand supplied the motor heats up more causing the thermal protection switches to act a little finicky which in turn shuts it down.Check how many amps the motor is rated compared to the breaker controlling the circuit. Is it a dedicated circuit only for the compressor or are there other things also drawing power from the circuit ?

Hitachi builds a very nice compressor, however suffers from the same problem that all brands will eventually encounter. Failure of the pressure switch. The pressure switch is a very hard working component of the unit. Depending on use, the pressure switch may cycle from as little as two or three cycles a day to as many as dozens per hour. The pressure switch has springs, contacts and unloader features that eventually wear out. The two most common failures are the contacts and the rubber diaphragm that acts against the springs to shut the unit down. Sometimes the screws securing the base of the switch the inlet port come loose and cause the problem that you are having. (The rubber diaphragm is between the base inlet port and the switch) Simple test is to spray soapy water around base of switch to check for leaks. Replace the switch as necessary with a SquareD brand available at www.grainger.com instead of factory unit to save money and increase life. You may have to make simple modifications however the money saved will be worth it. Choose a pressure switch with cut-off range between 120-139 psi. The higher the cutout switch setting you choose the shorter lifespan for your compressor. Your compressor works harder and gets hotter when achieving higher pressures. Try to use either no extension or shortest cord possible to max life of unit and compressor oil instead of motor oil to prevent carbon deposits. Good luck and email if you have questions about your Hitachi.

Might be a fault in the side stand sensor, you cant go far with the side stand out, or if the sensor has not sensed the stand is up.

Tips for a great answer:
Here are the most common causes of idle surge, rough idle esp when cold, other symptoms include stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
