5.4 triton engine sometimes looses all power

Hi. Hope someone can point me in the right direction. I got a 2007 XLT with a 5.4 Triton in it. It’s a wonderful truck, and I do my best to keep it well maintained. But I have seen this happen more than once. Very intermittent. I would be pulling out of my drive into the street and it feels like the engine dies for a split second or two, then it comes back to life normal as can be. I can’t reproduce it. It happens once every couple of weeks or months. No dash lights. Electronics are not resetting. So if it’s electrical, it’s inside the engine compartment. It doesn’t throw a code. No clue. Maybe this is how this truck acts when it misfires? It’s my first ford truck, or any truck for that matter. It seems like someone disconnects the power to the coils and reapply it real quick. Just a stutter. Then she runs like a champ. I would say it only happens when it’s cold. Within 5-10 min of start up.
