Car died for half a second....thoughts?

[QBee]

Saturday morning, driving to the start of the Peak Distruct run. Engine warm, about 10 miles into the cross counttry journey I was pulling away from a roundabout, changed to 2nd, couple of seconds later there was a jolting cough as if the entire engine had stopped for half a second, which threw me forwards, then the car carried on as normal.
10 miles later, same thing, same gear, same sort of speed/revs, again as accelerating.

Then did a further 130 miles of mixed driving, including several stops, no issues other than overheating in traffic, which I diagnosed as one fan with a dodgy contact below the rad.

Any thoughts where to start looking....or if I even need to?

Ps, it was similar to the cough well known by track-dayers, when you are down to 1/4 tank of fuel and enter a long left hander, ie g-force induced fuel starvation.

Thanks guys. I am reading all your suggestions and the next dry sunny day I am at home I will work through them all. Keep 'em coming please.

Attack date will probably be this Friday, as I have Daz (SiliconeKid35hp to you lot) booked to be at mine, plumbing in a new bath for Erin Dawes (to whom I am related by marriage). Shower man myself.

It will be helpful to be told in his bluff North Notts accent how I could do it cheaper, a different way, or whatever, while my head is deep in the passenger side footwell and my arse is in the air.....

It will make a change from my normal view of him working.....now where did I park that bike?

Interesting - the 80 amp fuse being cracked would do exactly what I experienced.
Never got a round tuit when Daz was here - he never felt the need to stop to breathe while talking, a common TVR owner/expert trait.
So I will have a look as soon as it stops raining

I keep taking the car out - no repeat performance so far. Busy with work all weekend again, but will gave another look through all your suggestions on Wednesday if it isn't pithing down.

The footwell area is often wet on my car - I will have a look at supporting the rats nest off the floor.

My battery was moved to the boot some time ago, so my wiring and ECU sit at floor level now. Good place to start my checking. Think i will send a grandson in, as he will fit down there. Good old Victorian values

That's handy to know Lou. Qbee do have a price list for hire of small persons, I think Paul and I will require one.
Can you let us know which type of gruel to make ;-)

I'll get you one. I have two of the little blighters at home, answering their mother back and spending half their lives on time out. I will get a price list in Magnums, as that's the currency they use for rewards, given that the pound is in free fall.

I'm with you there. For all the other mods I have done, I am still on the standard ECU, albeit remapped. Car runs fine and produces sufficient power for my needs. Including track days.

So I cannot catch cars with more bhp on the straights......bothered? Not me. I just concentrate on carrying more speed around the corners and getting a faster exit speed. This actually adds to my fun.
