repost (G10 Van stalls when hot)

well heres whats wrong.

it stated with some sputtering so I thought maybe the carb needed to be cleaned

so I got a carb kit cleaned it good put it back on started the van seemed fine then at op temp when in drive it will stall.
1982 G10 1/2 TON VAN
6 Cylinders 250 D 4.1L 2BL

I did do a Search and found that some times it could be the Ignition control module.


any idea???
