Afternoon guys,

Travelling on motorway today, cruising at 70mph and engine shuts down, no warning lights, didn’t want to fire up. Didn’t over heat, plenty of oil and coolant. Left it for 20 minutes and fired up, same happened at 10 minutes later at 50 mph, but could crank it back up. In fact happened a further twice. Any ideas? Thanks in advance.

When it shuts down, does everything go off or are things like stereo / dash lights still on?

If it the engine just shut off, you'd have alternator (battery) light and oil pressure warning etc.

Battery ground connector?

I'm thinking fuel pressure, possibly a failing fuel pump. There is also a chance of a crankshaft sensor beginning to fail.

If it was a straight cut, as opposed to spluttering etc, crank sensor, or more likely wires to it.

Since I may have scored 50% on this question do I qualify for a Monkfish apprentice badge laugh

Used to have the same problem and The Fish diagnosed faulty throttle body. Cleaned it out and has been fine ever since

There was a lot of gunk build up around the butterfly. Might be worth a try

A few others have suggested crank sensor. Think I’ll start there. Cheers

Then you are in just the right place.

Suggest that you contact Carl Herkes at LS Performance if you need any assistance on this.

Thoroughly recommended,

I’ve tried calling the mobile but no reply. They don’t seems to have a web address with any other contact?

If it happens again it might just be worth opening the fuel filler cap - if it's not venting properly it can cause these symptoms - including the shorter distance you can drive before it recurs.
