[Healeys] Two hot too shart?

[pennell at cox.net]

Listers,

I have been having an issue with the BN7 for a couple years now.  It seems that in hot weather driving that once the temp guage reaches 190 or higher that it does not want to idle too well and will cut off.  It is impossible to restart for a while after this happens.

Also, if I stop for a bit and say go into store then restarting is impossible.  When I come out the guage may read 212 or so.  This is what happened today.  After about 20 minutes cooldown and the guage dropped to 190 it started right up and I was on my way.

Other than this the car runs well under all conditions.

Any thoughts out there?
