I have a great little Rover 414i on a P plate, 45,000miles, and it runs fine 99% of the time.
At odd times, say every 30-60 mins or so on a long run, the revs die and the emgine cuts out for a split second - when driving it just seems to restart itself, when idling it simply stops dead - instantly, no choking or spluttering, it just stops and the rev counter goes straight to zero...
It restarts fine, and off I go.
This started two days ago, before that no problems for years.
There is no real pattern, and it is a very intermittant fault. Nothing else is affected, so can I guess at fuel starvation or electrical?
Any ideas what to look at? (I have a Haynes, and am not afraid to get dirty, but I'm no electician!)
