So was riding a few weeks ago on a 300 mile ride. About 2 miles from home, my abs, check engine and security light starting going on and off. Then all gauges turned off and then radio turned off. Revved the engine and they came back on. All this time motor running fine and strong. Got the 2 B codes listed below. I Also had a ton of U codes for lost communication with BCM, ECM, ABS....etc... This is a 2015 road glide special that has the ness risers and gauge relocation on them. They have been on for months with no issues. I totally rewired the bars with new wires and a brand new TBW as well as new left and right control packs. I replaced the BCM. Now the bike turns on, the fuel pump primes and all the gauges turn on. They stay on for like 3 seconds and then shutoff but headlight, taillight and turn signals work. No idea where to go next here. Battery and connections are good, stator is 3 months old. Could the ECM be bad? I doubt it as I assume I would have had motor issues but the bike was running perfect. Also checked the main grounds. Any tips on what to check next would be greatly appreciated. At a loss here and don't want to keep dumping money into guesses. Could the speedo be bad?

Can you check for DTC's?
I would inspect all the connectors looking for damaged pins or pins that may have been pushed back.
Are you sure the battery is good? Hook a meter to it and with bike in neutral, jump the starter and see what the voltage drops to.
The problem is that I can't get the bike to stay on long enough to have the technoresearch software connect. Bike comes on fully for about 5 seconds and then everything shuts off except headlights, tail lights and turn signals.
