Car loses power and switches off on hot weather

Ok it kind of stalls. It manifests itself whenever it's very hot and I have to apply the brakes to stop the car for a brief period. After stopping for that period (e.g. at traffic light or a hump), whenever I try to accelerate again it'll only make it up to 15 mil/hr and not more irrespective of how much i press the accelerator. If I try to continue with that speed it'll usually switch off and come to a halt. I usually get around this by switching off the engine and let the car cool for a few minutes. Strangely enough all this happens at the normal engine temperature. That is, the car does not show any overheating.

Hope this adds some clarification. Thank you.

My car switches off when i press the clutch & brake. This happens only when my AC is running.

i have the same problem with 2002 jag.i took it to jag who did a diagnostic test on it and gave me some fuel treatment which did not work.mine does it when its hot though it does not overheat.it sounds as though there is a blockage in the system that lets air out or that lets fuel in or the movement of water.i am sure its one of this but i have had the exhaust checked and its said to be fine.there is no warning light so i am really stuck.i cant even think of driving a long distance and every expert is saying my car is fine.i guess the problem is that none of them has actually seen it in the power lose state as i cant risk to push it to a halt before i get to were i am going i have the same problem with 2002 jag.i took it to jag who did a diagnostic test on it and gave me some fuel treatment which did not work.mine does it when its hot though it does not overheat.it sounds as though there is a blockage in the system that lets air out or that lets fuel in or the movement of water.i am sure its one of this but i have had the exhaust checked and its said to be fine.there is no warning light so i am really stuck.i cant even think of driving a long distance and every expert is saying my car is fine.i guess the problem is that none of them has actually seen it in the power lose state as i cant risk to push it to a halt before i get to were i am going
