Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 11 months ago.

There are several possibilities, but with that engine light on, that's your best clue to getting the reason. I would attach a scan tool and get the codes next.

You can have an ignition module that is failing when it gets hot or even a fuel pump armature can cause this.

Thanks, Ron

what type of scan tool
Expert:  rpmdiag replied 11 months ago.

Any kind will do, and you can borrow one from most parts stores for just a deposit.
