1993 dodge caravan 3.3 v6 on days when outside temps are higher than 70 degrees after driving for a while if rpm's get below say 1200 car will stall out and after 20 mins. it will restart but will stall...
What does it do, if you try to accelerate when this starts to happen? If it dies,sputters or is sluggish, I'd start by changing fuel filter, and if that doesn't help, have fuel pressure tested when (if at all possible) this begins to happen. Had similar problem, winter was fine, hot weather it would die, and restart after 20 minutes or so, then go a fair distance again, then same thing. Fuel pump was on it's way out and when it got hot, fuel pressure would drop. First thing in the morning when fuel in tank and pump was cool, ran like a charm, but on way home from work, after sitting on a hot day, fuel got warm/hot, and pump heated up and that's when it started. Carried a fuel pressure gauge with me. Fuel pressure when cool, was 49 psi, and when it got hot, eventually dropped off to 2 psi. Sat for 20 minutes, jumped back up to 49psi, took off for home,then would eventually get lower and die again. Changed pump and filter, all was well. Try filter first, you have nothing to lose, and it should be changed if pump replaced later anyway.
