Hi all.

For the last number of days, my 1988 740 GLE wagon has been stalling as I drive down the highway. It feels like vapour-lock, but I think it is too cold for that right now (-25 celsius), and it has never really happened before.

I will be driving along, and after about forty or so kilometres I will feel the fuel stop flowing. The revs remain at about 3500 rpm, but the accelerator is dead, and when I shift into neutral--the car is an automatic-- to coast off the road, the tach needle immediately drops to zero, and all the lights come on. I can then restart after only about thirty seconds or a minute. The same thing will recur within ten minutes or so, and then again, but I will finally be able to make it to my destination without further incident.

The mechanic thought that there might be something in the gas tank which was floating up and block the flow of gas, and I thought that I might just need a new fuel pump, but neither issues seems to be the case. (We did change the fuel filter just to be sure that that was not it.)

Is there anyone else who this has happened to? Does anyone have any other ideas?

Thanks in advance for any info you might be able to shed on this problem.
