1991 Pickup 4.3L S10 - acts up after 8 to 10 minutes and stalls out.

Just got a truck, and trying to figure out what is going on with it. It starts up just fine, and sounds like it is in tune. After driving it for 8 to 12 minutes it starts missing, and does not want to idle, you have to rev it up to keep it going at a stop sign, sometimes it will still stall out. It starts back up and then keeps acting up, if you let it sit for an hour or so then it will again drive great for about 8 to 12 minutes before acting up. Engine and tranny seem strong... any ideas on what is going on?
