Sounds like a fuel delivery problem to me.
Have you replaced the fuel filters?
It could be a weak fuel pump with low putput too.

No, but nobody gets paid to answer questions, either, so you have to wait until somebody happens along who has the time, inclination and knowledge to address your questions. (I have the time and inclination, but not the knowledge, for example.)
