My car stalls or just dies. I changed crankshaft sensor , fuel pump, etc..

Thank you for responding. Everything you said is what happens when it stalls or just dies.. I did have it tested and it gave ...p0335 ckp sensor (a) circuit problem, p0410- secondary air injection system, p0442- evap system small leak detected, that is just some.

You still have not had it "tested". Sounds like you have gone to a parts store and had the codes pulled so that parts could be purchased. So far that is not working for you. Each code has a set of tests that go with it. Each code can be a cause or a symptom of the problem. It requires actual testing of the system to find the cause of the running issue. I recommend finding a shop in your area that has the ability to properly test the vehicle to pinpoint the source of the problem. Once they can pinpoint the cause of the problem, then the right parts can be replaced and the system re-tested to be sure the problem is corrected.
