Evo ix Intermittent Electric fault

Every few weeks my daily driven stock 2006 Evo ix fails to start, normally after 4 or 5 days of not being driven but can also fail immediately after driving.
The ignition turns on normally then when I turn the key to start position everything blacks out, including power to interior lights and door locks.
The car powers up and starts normally again after disconnecting the battery for 30 seconds.
Any suggestions appreciated

I would try cleaning the battery terminals and changing the battery first

Aren't what you describe the classic symptoms of a failing battery cell or cells ie one minute you get full voltage and next minute it can drop to around 10 volts. Have you actually tried measuring the output voltage?

thanks Phil, yes I have checked the voltage output from the alternator and battery and both are normal. I also cleaned the terminals and replaced the battery but neither solved the problem. It seems like the disconnecting an reconnecting the battery resets something, perhaps a faulty relay ?

So you're saying the battery voltage is good even when the car won't start?

Might be worth checking it is not the infamous water in the passenger side wiring block issue.

yes even with the new battery installed or with jumper leads connected the dash instruments will not light up until I disconnect and reconnect the battery.

good tip, thanks very much. I have read though the thread and just inspected the connections and thankfully they all look clean and dry.

Chassis connection at end of ground cable (-ve) to battery?

thanks, I have just checked ground cable and it looks secure and untouched since the factory.

From my experience sounds like failing either ignition switch or wire connecting switch to starter. Very common in Mitsubishi Galant from mid 90s to mid 00s. Check switch for burned out pins or gunk residue. If OK, check if you have voltage at starter end after turning key into start position.
Very annoying and common problem haunting old Colts, Mirage and Galant

I had the starter motor push on spade connector fail a while back. However wire is more likely to fall out than be intermittant but worth a check.

If disconnecting battery always fixes issue then more likely that is resetting immobiliser etc. Does locking/unlocking doors also fix it?

yes the starter connections look secure.
it is not just power to the starter that drops. it everything including the doors locks. It will unlock when I come out to the car then will all loose power when i get in and turn the key. could be an immobiliser fault.

thanks I will pull out the ignition switch and inspect it tomorrow. The starter relay doesn't even click it, it is as if the batter isn't even connected even though the terminals are clean and secure.

When you turn the key to crank it disconnects the power to the "key on" circuits and that is normal. You need to check the battery voltage to see if that drops, if so then it could just be a battery fault. Try switching on the headlights, if they dim significantly when trying to start then again it suggests a battery issue.
