After replacing spark plugs SUV started running sluggish, it shut off and will not turn at all

No engine light. I changed the coils and spark plugs. Then it was diving weird and I got new ones. It started driving really good, then starred driving sluggish, then shut down. And it wouldn't turn at all. No lights on the dash or nothing. My uncle Junebug sd check the fuel pressure. Then I go online and research because I really need my car. My grandson has leukemia I need to take him to the doctors. Plus me I have a lot of appointments. My household depends on my car for everything. So I also charged the battery because it was on one of the to do list online, lol. So the SUV now has lights on dash and it turns but it still does not start. If one of the problems is the battery. I have warranty at Advance Auto. Anyways there is a little information for you. The battery is one year old. Hopefully you can fix it and it is not something major. But even if it is I need it fixed. Thank you so much.
