2017 5.7 Hard to Start

Hey everyone, new to the group and thanks for the add! I’ve got a 2017 Tundra SR5 TSS version with the 5.7 and over the last few months it has gotten hard to start when it hasn’t been ran overnight or for more than a few hours. Symptoms started with it kind of rolling over lazily when cranked instead of firing like normal and it has progressed to where it will barely crank and I have to bump the throttle and/or try cranking numerous times. When it does this the starter will continue to turn for a few seconds after I turn the key back off. I’m no mechanic but it seems like the fuel is draining back into the system when it sits for any length of time. No codes or check engine lights and runs like normal once it starts and will fire right back up. It’s getting worse and I’m worried it’s not going to start before too much longer. Any help/advice is very much appreciated!! Thanks guys!
