Coupe Stalling Problem

[Wolff <wolff_b@ix.netcom.com>]

Very occasionally, my "new" coupe will stall, but only when warm. I have
felt it stumble a few times and then it runs fine. Most of the time it
runs perfectly. It runs even better now that I adjusted the throttle
cable and WOT switch. It will usually restart if it sits for 2-5
minutes. If I turn the key, I can hear the fuel pump running, but not
loudly. I checked the ground on the intake side of the valve cover and
it is tight. 
Any suggestions?
TIA,
Wolff
