Sounds like a bad ignition coil.

>Here's the situation: My '53 Imperial, largely original with under 70K

>consecutive days in '97, after a lot of work on my part. I recently had

>But here's the problem: Driving it home in September in low 90 degree
>weather, it "vapor locked" after about 10 miles of driving, and 6 more
>times until I got it home, which was about a 20 mile trip. Each time, I
>would pull it off the road, let it sit for about 5 minutes, and it would
>easily start again, no sweat. Then, about 1.5 miles lately, just like
>clockwork, it would do it again. And over and over. I'd step on the gas, it
>would stumble, and then...nothing. This was scary, being in metro Detroit
>traffic. I even bought 2 pounds of ice at one stop, and packed it around
>the fuel pump, but I can't say that it helped. The power steering goes too,
>of course...This beat a workout at the gym, since I am more of the distance

>I was lucky to get it back home.

>A couple of weeks later, with the temps in the 70s, I drove it again. It
>went about 10 miles or so, maybe a bit longer, and it stopped again. This
>time I was pretty close to home, so I got it back OK. Started readily after
>the usual 5 minute wait.
>
>A third time, it was in the 50s or something. I only drove it less than 10
>miles, and no stalls.

>Is this definitely a fuel pump problem? If yes, is a rebuilt one to be

>one?

>Any opinions, advice, will be appreciated, and thanks in advance.
