Have the engine computer scanned for trouble codes. Misfires are from loss of fuel, spark, or compression. Check the fuel pressure, check that all spark plugs are getting spark, and if all good so far, test engine compression. Low compression in a cylinder will cause misfires and loss of power.

It could also be a vacuum leak- a loose or cracked vacuum hose or an intake gasket leak.

I would check engine compression, fuel pressure, catlicit converter as it might be blocked. Is the transmission/gearbox OK?

check fuel pump.if there is a small , even hairline crack in the diaphram it will do as yours does. good luck.

Could be low fuel pressure, or a long list of other things.
Is the check engine light on ?
Does it feel like it is running rough, or starving for fuel ?

could be the bad catalytic converter.

this sounds like a fuel pump problem,but i cant advise without stripping the sender unit and haveing a play so to speak

yes get it tuned!

Replace the catalytic converter and EGR valve

adjust the valves .006 intake, .010 exhaust.
