Engine shut off while running and would not restart?

The car would shut off while running or if I drove and turned off it wouldn't restart for almost an hour. Changed crankshaft position sensor and it helped high idle and my brakes weren't super stiff anymore they work normal again but still same problem no codes. I did some doctor Googling, and everything pointed toward the issue with distributor. So, I ordered a new one and now the car won't start. It has spark and I can hear the fuel pump pressure. The dash lights up but all lights go out except the oil light so I changed oil and filter light stays on but will disappear while trying to start car. No check engine light either. I'm lost very frustrated not much money and I'm no mechanic but learning as I go. The car listed above is a convertible. Help me please
