I assume you have a P337G??
This sounds like one of the uplock switches is intermittant?
However if the HYD motor keeps running after the gear is up and locked, it looks like the power pack is not getting up to pressure to shut it off.
Are you sure the nose gear is up and locked.
Check the 28 volt on the motor, make sure there is no voltage drop from the contactor or the circuit breaker.
That is with the gear operating.
The pressure switch on the power pack are a source of problems, you best bet is to replace it, as it is a sealed switch.
The amber light is controlled by the uplock micro switches, any switch that is open will cause the amber light to go out.
Do all the gear doors close up propely, with the gear both up and down?
Let me know how you get on.
