I suggest you check your fuel pressure and your Mass Air Flow Sensor (MAF). The fuel pumps and the MAF often fail causing these symptoms, but there may be other issues too. I suggest you take it to a qualified mechanic to avoid replacing unnecessary parts, since there are several possible problems.

Motor stalls on any accelaration

This can be caused by a faulty camshaft position sensor or idle air control valve (IAC). It wouldn't be a bad idea to have your engine codes read. But this is usually the cause.
