hmm.. that's really hard to diagnose without doing some tests. are you getting any "check engine lights"? get a scan for fault codes that might provide information to the problem.

there can be many, many things that could contribute to this type of problem.... clogged/failed fuel injectors, failing MAF sensor, failing ignition coils, etc...
