Engine shut off while driving on Interstate, cranks but no start

So my car listed above (DE model) cranks but wont start. I was driving about 65 mph on the Interstate and out of no where I heard a faint pop sound like the sound of pressure being released, then the engine shut off. Since its a manual I put it in and out of gear and pumping the gas but it didn't respond. I got it to coast off the exit ramp but once I parked it, it would start back up. Cracks but nothing. I had it towed by my insurance. Prior to this it did have an engine light for P0400. I don't feel like it could be related since that has to do with ERG, but i'm not entirely sure. It was also burning oil. Not bad but it would emit white smoke when you accelerate hard from stand still. Anyone have any ideas where I should begin? The battery is fine has plenty of power. I'm thinking it could be the fuel pump or fuel pressure regulator. Cranks but pumping the gas doesn't seem to be doing anything. Like it not getting any fuel. Since its my old car and has been reliable for so many years I want to do what I can to fix it. At this point it's like a member of the family, haha. Anyone have any suggestions?
