Well, the simple/free things are fuel flow, air flow, spark. Perhaps throttle body. You should check the module Morris suggested to see if it looks rusty/damaged, MAF sensor, test battery, check plug gap. There is a sticky at the top of the forum about shuddering issues that are more extreme. If you find it is fuel related, it could be the pump dying. That isn't common, I don't think, but certainly possible.
I would look into the fuse 27 tsb, anyway. Silly this isn't a recall, but what can we do... https://www.f150forum.com/f38/2009-2...-issue-372139/
