Warm start prob. - Not accumulator

[beecher@xxxx]

Hi Folks,
I am now a proud owner of an 81 (~35,000 miles), and while I love 
to drive it, it has been stranding me lately. It starts fine when 
cold, but after I've been driving it a few miles, then turn it off
and 
let it sit more than about two minutes, it won't start again. It
turns 
over, but doesn't fire... it seems fuel starved. I have to let it
sit 
for several hours before it is back in the mood to run. I read the 
archives, and was pleased to find that others had solved this problem 
by replacing the fuel accumulator, which I have now done. Then it 
stranded me again, doing exactly the same thing. My mechanic (very 
familiar with Ds, Haglin in Boulder, CO) says that the fuel line is 
holding pressure VERY well (better than usual, apparently), so he 
doesn't think there is any problem with the value in the fuel pump. 
He's pulled the injectors, and they all appear to be working fine. 
He's stumped, I'm stumped, I don't know what else to do. He's still 
looking at it, but I thought that if anyone had any suggestions, I 
would be pleased to hear them. Thanks to the contributors for a
great 
list!
