Welcome to JustAnswer, my name is XXXXX XXXXX X'm here to help get your problem resolved. Ask follow up questions, thanks. I've sean this often caused by a failing mass airflow sensor, clogged fuel filter, weak fuel pump, and oxygen sensor. Monitor fuel pressure and make sure that under a load or during the problem, fuel pressure is going over 60 PSi, check for vacuum leaks and clean maf with cleaner from parts store.
how can i tell if it is the maf
If it runs rough you can see if it runs better disconnected if so its probably dirty or bad, otherwise no easy way to test..But it usually sets other codes so I'd replace that if fuel pressure is good, no exhaust/vacuum leaks, injector cleaner doesnt help, and oxygen sensor doenst help.
