engine stops

I have a 1983 gmc ext cab 4x4 with an Iroc 350.
Question is when you step into it it will either quit or wil go to an idle and you have no throttle until you shut it off & restart.
ANY IDEAS?

It is tuned port injection. It ran fine for awhile. Just started about 2weeks ago.AS soon as it does it you can shut it off & start it right back up. It only does it when you get into it.

OK Truckman; Please give us as much info as you can about the engine. Like carb or injection? Has it always done this since it was installed in the truck or did it just start after running right fer a while? Thanks we need info to Help.

kinda sounds to me liek you arent getting enough fuel.

MAS ? or the TPS are the most likely culprits .....
