Default Missing and popping

I have a 08 Ultra I have installed a Thunder Max on. It has around 300 miles on upgread running better than ever. On a ride yesterday it started missing and popping acting like it was out of gas. After a few miles the engine light come on and it ran great while the light was on. I stopped and filled the tank and let it cool down and started to ride again about 5 miles it started all over. Never stalled or quite running. Any suggestions?

I Assume you replaced the stock exhaust? Factory map settings for stock exhaust are very lean and if you didnt comphensate with a tuner of some sort, mabe running too hot now from the extreme leaness?
