1996 Ford Ranger, 2.3 4 cyl, 300,000 plus miles, when accelerating, a/c stops blowing out of vents and blows out defroster vents. Also, when driving in hot weather, I can go about 30 to 50 miles, then it starts lugging down, backfires, eventually dies. Will crank, but will not start. I usually have to wait 1 to 2 hours (depending on air temp). It will finally start and run, but will do the same thing again until the air temperature cools off. Have replaced fuel pump, fuel filter, and checked catalytic converter. Checked for codes, found none.

I would look at fuel pressure. If it is low, it could boil causing vapor lock

U have a vacuum leak some where. Check all the vacuum hoses if u cant find it. Get 2 cans of brake cleaner. Start under the hood spray all the vacuum hoses down when u find the leak you will hear the idle pick up while u spray it. We need to know what the fuel pressure is when it quits. Does it have spark when it quits? Will it try to start with starting fluid?
