Sorry for the delay on getting back to this issue. Problem was failing spark plug wires. I replaced them last year, but they've already gone bad. I located two wires that had started arching into each other. I replaced the wires and plugs and all is well. The problem became much more apparent after I washed my truck. The mis was much more noticeable and easier for me to figure out. Thank you for all of your help.

Now to figure out how to get this damn plug out of the block for my oil pressure sender. Stripped allen head plug....
