My motor is dualport fuel injected. Okay, well every time I apply my brake pedal when coming to a stop, it dies out on me. I would have to turn it back on again and it would start up fine. I would have to push my brake pedal on and off so it wouldn't shut off while I'm driving. Could it be my brake booster, IACV, or vacuum leak? It would be very helpful because it's my only car. Thanks.

Checked brake booster for leaks. Tried the booster check procedure, visual, and soapy water check but no leaks detected. Plus, no engine light, but fuel light came on though when braking and car shutting off. My fuel gauge hasn't been accurate since I bought it a year ago though. So added fuel and car drove fine. Braking with full tank works fine, but later on about half the week it acted up again. So my car works fine with a full to almost half tank. Is it my injectors, or fuel pump unit? Or just try to replace the booster and see what happens? Thanks bro.

Check and cleaned my throttle body and IACV too so those are good. Looks good too. I'm pretty sure it's a vacuum or maybe fuel situation. But well see huh.

Sorry it took so long. Hadn't had time to fix it and money wise. But yeah, the booster is not the problem. Fuel? Wiring? One of those. Only works fine when full to mid gas tank. After that when brakes applied hard, it dies. So I basically have to fill it up every half tank. Sucks.
