Had total ignition shut down last night on my 5.3 V12 after being stuck in motorway crawling traffic for an hour. Managed to pull onto hard shoulder. Embarrassing.
Seems everything under the bonnet got too hot for something and it shut down (water temp was fine). Engine recovered life after 5 minutes.
Pretty sure it’s not fuel related as the car restarted on the button, with no cranking at all required – also we’ve just had the surge tank filter and fuel filters all changed.
We successfully completed the remainder of the 300 mile journey down from Manchester to Eastbourne without issue
