Awe man, that bites cuz it could be a bunch of things. I'm no mechanic but first thing I would check is your alternator. You might be draining that battery the whole time you are running. Not sure when they stopped making switches for lights under the hood but check and make sure it wasn't left on. Don't forget about the dome light, cuz you wont realize it until your vehicle doesn't turn on at night There are others like relays and stuff but I could probably get you hurt. Good luck bro

I would take it back to the shop that put the pump in. Could be a bad pump or they could have pinched some wires.

do you use a phone charger in the vehicle?
if so...disconnect it every time.

Could be a bad battery..

My dome light used to come on regularly and drain the battery when I wasn't in the truck. I pulled the fuse. Come to find out it was the door switch.

Bad battery, alt not charging, light switch being faulty, or a short. Electrical problems suck.
