I have a friend that has a 1992 4.3liter Merc. with a 2 barrel carb, that will start fine, but will only run for about 1 min. sometime 2mins. then cuts off. When it does cut off it will restart right away, but will only run for a min or two. Does anyone have a idea what I can look for? Thanks in advance.

Same problem a friend had with a 97 4.3 his was a bad oil pressure switch. I believe they called it the Hobbs switch...? Same symptoms as you're describing... Might be worth checking out.
