Starting problem

Try changing the coil 1st...sounds more electical than fuel/timing..would chk timing and adjust the carb for gp...but if it starts up and runs good til warmed up and shuts off, and when you let it cool down then it goes again,then i would suspect spark problem and could very well be a combination of things,if dist has 100k+ miles on it then ditch it and get a replacement,had this same scenerio occur on 3 diff trks/ram/chgrs...after replacing everything related to fuel including new fuel lines from front to back and a new edelbrock carb and intake,fuel pump/filter even adding an electic inline as backup still had same prob....coil fixed it on 1 and coil and dist cured the others...coils get hot and if they are cracked it opens the crack and all firing stops and same with a dist with a faulty pick-up coil plus the fact that they are prob worn out...a skip white perf hei dist and coil are worth their weight in gold for all the troubles that you can avoid plus the fact that your brainbox or engine controller can act krazy like this and the hei dist eliminates that pos also along with ballast resistor...they are cheap and totally eliminates these kind of agravations and they are cheap less than 55 bucs to your door [dist] just look up skip white perf distributors and you will find them on the net...I will never run a fact dist or brainbox/bal res on anything i plan to keep again...just my 2cents...and the facts...
