Electric issues

Last night coming home, the car lost most all electric power. It slowly died and the lights dimmed until it came to a complete stop. Probably over a mile or two.

Whilst I was calling the breakdown people, we tried it again and it was fine, started right up. A few miles down the road it did the same thing.

We got into a pub car park; lights were very dim, wouldn't turn over and the wipers were on massive go slow; so seemed like a flat battery.

Sat in a pub for an hour waiting for the tow truck, and on coming out, it started straight up, full power. We ran it for 15 minutes, and all seemed fine. The tow truck followed us home for 10 miles and no issues.

I've check the connections etc, and it all seems fine and starts no issues.

Anybody got some bright ideas? Clearly there is a problem somewhere but I cant spot anything, and I don't really want to just start replacing stuff, with most likely culprits being battery and alternator I guess.

Cheers

 

Thanks all.

A few points there I haven’t checked; most notably the connectors under the air box, didn't know about those so good to know.

I’ll go through the above list later this week when I get backend let you know what I find.

Appreciated

 

Went through the list and all good. Only two things I found was a positive wire behind the foot well fuse panel cut but not taped up; I think this was me when I took the immobiliser out. And some oil on the alternator; I’ve got weeping cam seals.

Run it a few times now and no problems.

All I can think of is that when I parked up at a friends house it was on a slope, nose up and that a little oil might have dripped onto the alternator and upset it! We will see, a few long runs coming up over the next few weeks so fingers crossed!

Thanks for all the suggestions.
