96 civic
starts right up but will shut off in 30 seconds unless i hold throttle over 2000 rpms for at least 1 min then it will stay running
when it dies it just cuts off like i turned key off
before i found high rpm trick it would die 30 sec then 20 then less till it would only crank
what was also odd was when it got to the point of not starting the spark( while some one was cranking it) was intermittent
won't even start on starting fluid

 

Post all CEL codes stored in the ECU.

 

no codes

 

Details? How did you test for codes and what result indicated no codes?

Are you saying that when engine dies, all warning lights in the cluster are OFF? If so, the issue is likely the ignition switch.

 

my code reader said 0 codes and check engine light is off
i wont be able it check dash lights till next weekend but i am sure they come on as usual when engine dies but i will check
thanks for your help

 

I highly recommend a full ignition system tune up.

Also do the following:
Remove the distributor cap, rotor, dust cover, and coil.

Take the coil into you house to let it come to room temperature.

When it does, do the Ohm tests in the diagram.
