Hi Peggy my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
With the hesitation and stall out issues here this sounds like the fuel pump is becoming weak causing this issue.I have seen fuel pump act up like this here before causing the issues you see here.This can cause a lean engine rattle noise like you heard and as it tries to stall out the lights on the dash can flicker.I suspect the fuel pump is on its way out needing replaced.
The fuel system will need tested to verify this which will require a fuel pressure test gauge as well as a multi meter.The pump itself can run around $200 to $300 and 2.7 hours labor to have replaced or a total of around $500 to $650 for replacement.
