Spark plugs can be "fouled" quickly under certain conditions, such as using a plug that is too "cold". residue can build up on a cold plug and foul it out. Try running a slightly hotter plug.

Example: if the # on your plug is B8ES, change to a B7ES, which is a plug with a hotter tip temp, which will burn off the residues that are fouling it.

It could be running lean, which causes excess heat to build up in the cylinder, causing pre-detonation & excessive heat in the electrode, either burning away the electrode or causing the actual center of the plug to overheat, & contact to be lost, check yer mixture mate!

Spark plugs do not `die' they just become inefficient when clogged-up with residue. However, the spark can die when the ingnition system is faulty. Back track through the system and eliminate the possibilities one by one (i.e. Battery, ingnition system, HT lead.)

OK. Try your HT leads and also make sure that your spark plug caps are OK.
