Having trouble with my 2019 883Xln

I've got a 2019 883Xln that's been acting up and it's my first Harley and EFI bike. About 4 months ago, I was out riding when the bike started surging and losing power every few minutes, I thought it was a fuel issue, so I replaced the fuel pump, filter, and O2 sensors, but no luck, if anything, it's gotten worse. I tried new coils, high-tension leads, and spark plugs, but the surging is still there. I'm thinking it's something with the ECM or pulse points. Anyone else had this problem?
 
It seems like you've done a great job identifying and replacing crucial components! Given the situation, it might be a good idea to get a pro to check it out, particularly since the ECM or pulse points could be at fault. Someone with the right diagnostic tools can evaluate the ECU and sensor readings to find the real issue. They'll be able to determine whether it's a software glitch, a faulty sensor, or another problem that's hard to detect without the proper equipment
 
I ran into something like that with my Sportster, I replaced all the usual stuff...fuel pump, O2 sensors, plugs but it kept surging. Guess what it was??? the damn ECM, so I got it scanned, and problem solved after a software update.

I am loooking towards having a pro take a look, I just wanted to make sure I wasn't overlooking something before heading down that route

Well dang, wild! I'll get my ECM scanned and see about that software update, I didn't wanna jump straight to a dealer, but good to know it solved your surging
