Engine's off when stopping.

Guys anyone experience on red light or stop Xing. When applying the brakes it turns off. Red top on a 90 chassis.

Thanks

A lot more information would help (engine, mods, does this only happen when stepping on the brakes...)

I’ll throw this out with what you’ve given.

If this is happening when you step on the brakes, it very well might be your brake booster leaking. Your brakes use vacuum assist from the engine. If your booster is leaking, you’re creating a large vacuum leak when stepping on the brakes. A slight leak will cause the engine to stumble, and a large leak could cause the engine to die.

Good luck.

Maybe your alternator is on it's way out.

Or a very weak battery
