Can be caused by several factors and need to narrow down when it happens and what happens.
Such as does it start fine? Idle fine? Any warning lights? How long has this been happening? Is it different on a flat road v going up steep hill? Have you been using it regularly with regular refuelling? When was fuel filter, last changed?
See if any error codes are reported (you'll need to plug in a code reader and even the cheap ones that work with apps give basic code reading) and clear the codes and see if same codes come back as you can get old codes still in the memory and also different codes reported - from experience diagnostic codes are not 100% when fault finding.

Have you checked Broken coil pack or injectors
Sounds like cracked coil packs
Hi Cris,
I agree with all of the above, in particular Marc’s suggestion to plug-in some appropriate diagnostics to get a better idea of what could be causing your problem otherwise you’re just shooting in the dark.
You could try cleaning the MAF sensor, or just disconnecting it [the engine will run in a default mode], and check for leaks in the induction system.

Generally coil pack, MAF and injector faults would give symptoms across all running / driving, rather than just acceleration lag / hesitation.
Hence, need to narrow down the symptoms to what happens and when it happens and methodically work from there and use diagnostic codes to help.
Otherwise can end up expensively replacing parts without solving the problem.
