Scan for error codes first. Can be a dozen things.

Plugs/maf won’t hit suddenly and dramatically.

A guess would be cps as that's been the main culprits for me on m62tu.

You prob have the n62 which put the cps in the back i don't know if the different type has similar failure modes but with twice as many twice the chance of one messing up.

Miles on the odo?
