1983 S-10 1/2 ton running problem

[Bobandbadger]

Hi I just bought a 1983 Chevy S-10 1/2 ton PU 4X4. I start up truck and it runs fine but after about 15 minutes when i go to stop for light the truck will stall. I sit there for a minute and try to start again. It will start but you really have to put your foot all the way down on gas pedal but after it starts it runs fine until the next stop. Anybody have any ideas what this might be. Thanks Bob

When it quits check for lose of spark or fuel.

Lot of problems in the dist with pickup doil and dist module.
Parts places can test dist module.
