Ford Ranger switching off!

[PeteB]

Four times recently,  my Ranger has switched itself off in straight and level flight, twice recently there has been nothing on the key when I've gone to start it - 30 mins later, it started no bother!

 

Its in the garage today - any bets that the battery or alternator is found to be faulty when they both tested 100% by the AA?

Well bugger me. Gone outside to go to the garage and it won't work! AA called....

What year is it? My mates 2009 Focus turned itself off, especially on motorways. It was diagnosed with a turbo fault, and renewed, still did the same, took it to an indie garage, they diagnosed something else, had it done, still the same, sold it in the end.
Turned out it was a duff crank position sensor, engine wouldn’t see it. Not sure if that’s the truth, that’s what I was told by the my mate, who knew the new owner.

Turns 3 and done 103k soon. Getting bored by it tbh......

Looks like that may be an issue with the positive feed into the fuse box under the bonnet. The AA chap has seen 4 recently and the garage has done 2 recently. Corrosion in the contacts, melting the plastic box etc or just an intermittent loss of power etc. An hours labour and circa £110 for a new box, plus the inconvenience!

That's what I was just going to tell you to check glad it's sorted
