Why does your car stalls when i go over 70 mph and slowly break?

Your car may stall when you go over 70 mph and slowly brake due to several potential issues, such as a failing fuel pump, clogged fuel filter, or ignition system problems. At high speeds, the engine requires more fuel and air; if these are not adequately supplied, the engine may struggle to maintain power. Additionally, issues with the transmission or vacuum leaks can also contribute to stalling during deceleration. It's advisable to have a mechanic diagnose the problem to ensure safe driving conditions.
