Car starts then dies after sitting overnight

So i got my new engine in and it drives, but if the car sits for more than like 6 hours overnight it will start then dies right away. If it runs though i can drive it all day and make hr stops or a few hr stops and it starts and drives mint. But when i go home at night and it sits, the next morning it starts and dies. And if i continue to keep starting it, it just starts then dies :( The engine was flooding yesterday with gas and my gas gauge has been acting up lately. Going from quarter to gas light on, then after a min it goes back up a bit and down. Not being really accurate.

Im really thinking its the fuel pump going out. Any ideas?
