spark plugs, coil pack, ht leads and if none of those checks reveal anything then do a compression check on each cylinder to check a valve hasnt burnt out, etc, that would be unlikely tho. first place to start is by wacking a new set of plugs in then check the spark from each lead if not.
see how you get on.

do what he said do a diagnosic check first

change sparks
coil parks
HT leads in old ones
Compression test each cylinder
check the injector duty cycle is correct and also if theres a build up in them
