Perhaps the plug caps and leads could be the problem, seeing as they've been tugged at to get them out the way to get to the spark plugs, could have caused on of them to crack at the end or something giving a poor spark which you would only notice when under load/heavy load.
But as Deadeye said try the air filter first as it's probably easier to see if it's the problem.
