Good to hear from you!
My money is on spark plugs and wires. Typically aftermarket wires are good for about a year or so. There location on your engine makes them very prone to failure.
When you do the little test I described, if you feel it popping / hesitating, then it's time for a new set. Be sure to change the plugs + wires, and make sure there is no oil in the spark plug tubes.
Let me know how you make out with the quick test, and we'll go from there.
