Vy commodore randomly cutting out while driving

[No9]

Hi people need some advice and sorry if this has been covered before. We have a 2003 VY V6 Commodore and in the last few days it has cut out will driving, we get no warning it looses power to all instruments yet it will start straight away and continue. It is completely random and we get no warning lights. The battery is only 6 months old and i have checked and cleaned the connections, any help would be much appreciated.

Loosing power to the dash meaning no gauges or function or just stalling?

It just dies.. i havn't noticed any warning dash lights etc but last night when it died i noticed the interior light turned on like when you turn key off.. could the ignition be faulty?

Just a bit more detail to help us... the instrument cluster LED display is still working when it dies ? (as gohrdrgomad said - is it merely stalling, or is the entire dash display screen dead - ?)

Also are low revs (taking off from the lights) or high revs (along the highway) a factor ?

interior light turned on like when you turn key off.. during day or night?

I had that before. Checked everywhere and it traced back to positive wire where it bolts to the little main fuse had come loose. It's hidden under a plastic tab.

Worth checking it's tight.

It can be quite a few other things though.

Just an update it ended up being the ignition switch,$ 49 from ebay and all is sorted.
