Am I the only one that got distracted by this comment?

I’ve got a similar issue going on with my 73 C20, I can tap the brakes and she shuts off, all power stays on just engine dies, replaced booster and check valve and all it does is stop better, I found that only after she does when hitting the brakes is she hard to start, have to hold full throttle in order to get it to start but can then kill the ignition and she’ll start right back up like nothing happened, still need to read everyone’s responses but curious if anyone can think of a fix? I can put her in neutral and come to a stop just fine but if it’s in gear then she dies
