Car stalled out and wouldn't start again, had towed, more problems now?

What is your question?

So first, I had my oil changed at meineke yesterday. I've never been there before but I couldn't get in with my mechanic so I just figured I'd do it quickly. Things were fine after that, I drove to work and when I got off work 7 hours later I started the car and it went into drive; drove maybe 10 feet forward and appeared to stall out. Which I thought was odd since I didn't fill the tank(stalling is occasional due to charcoal cap which was already addressed and a common problem). When car stalled, I let it sit a minute and turned the key; it just made the starting crank sound like it couldn't turn over so I held it past for 15 seconds, did that a few times and nothing happened. A friend came to try to jump me since battery light was on, nothing happened since battery was tested and good. AAA came and towed it, my mechanic looked at the car(very trusted guy we've been using for 6 years). He said fuel pump was bad. He changed the pump and started the car, now all lights on the dash are on. He is keeping the car to look more into after the long weekend to find the problem. Does anyone have any idea what this may be or have any of you with the jeep patriot experienced this exact problem after changing a fuel pump? Thanks in advance for any input and advice- just trying to figure out what I'm getting into cost wise. My car is a 2007 Jeep Patriot 2.4L automatic. 119,300 miles. repairs done; I've had the car two years(my first car, I'm 19). Summer of 2015 I had alternator replaced. December 2016 I needed upper tie rods replaced. Other than that I can't think of any problems fixed, always passed inspections, oil changes always done timely. It's always been a good car, I just can't figure out what it could possibly be.
