Engine cutting out

[peanut450]

A few times when driving the engine cuts out all the dashboard lights come on and after @20 seconds it "bump starts" and the engine is back working.( no error codes)
This has only happened on a 3 blob hot engine and at a steady 60 mph.
From searching it seems the crank sensor could be at fault .
Any other suggestions ?

Crank sensors tend to stop the engine running when it's idling then not permit re-starting until a few minutes of cooling have elapsed.

I'd check the big electrical connections - the earth leads in the engine bay were always a bit lame on these cars.

I find this very useful based on the above reply, nice upgrade on the original, the disconnect makes it easy (have one, will buy another for car no2)

I will look over the earth leads at the weekend in case they are bad but I remember checking them @ a year ago.
Thanks

Battery leads also.

[peanut450]

Have taken the earth leads off and they were all were clean from the last time I did them.
I have added another earth lead from the same earthing point as the braided one . I remember reading a suggestion that adding an earth cable to the bolt that holds the dipstick tube could improve the earthing.
I also replaced the valve on the breather as it had become a 2 way valve- could this have caused a problem?
Thanks

I earthed mine at the dipstick tube - to earth the ignition coils rather than them earth through the head gasket interface and Loctited bolts.
Breather valve shouldn't have caused your problem - but needs sorting so as well done.

You don't have a jailer's key ring on your ignition key do you?

[peanut450]

Just ignition key- no key ring jailers or otherwise

This week it happened 3 times. Twice as before @60 mph engine died then restarted- quicker than before in about 3 seconds.
The third time was at a set of lights so was stopped when it stopped . Started straight away .
Have found some fault codes using a delphi reader .
P2040
B1020
B1014.
Have hopefully cleared them so will see if they reappear.
Thanks

[Thrumbleux]

What do the codes relate to as descriptions?

[peanut450]

P2040- Evaporator to hot . I assume this is a/c related but I do not have a/c.
B1020- No CAN message from control unit Engine control module
B1014-No CAN message from control unit Engine control module Instrument Cluster
So maybe a dodgy connection on the SAM or instrument cluster ?
Any thoughts?
Thanks

[Thrumbleux]

Just had a look at FQ101 but P2040 not listed. AFAIK, P denotes powertrain. Not sure is AC comes under powertrain or not.
Dodgy connection plausible. Engine control module (MEG) is the one incorporated into the air filter box. I think I'd look there first.

[peanut450]

Have finally managed to dodge the showers and have unplugged and plugged the two connectors on the MEG.Could not see any corrosion .
Cut out twice this week once when cold after about 2 mins whilst stationary waiting for a gap in traffic and also at slow speed when hot .Did not bump start at slow speed but restarted as soon as I stopped and tried the key.
Will see how this week goes .
Thanks

[peanut450]

Lasted for 5 days before cutting out at low speed so did not bump start.
Restarted straight away .

Crank sensor is not exactly an expensive part, so I would change I would change it just to eliminate it from the list of possible causes.
