Expert:  Amedee replied 1 year ago.

Thanks! Please try and find out what the fuel pressure is at when this happens. Talk to you in the morning!

Customer: replied 1 year ago.
Ok I will call the shop that has it and ask them to check it for me.
Expert:  Amedee replied 1 year ago.

Good morning and sorry for the delay! Was the distributor assembly replaced? If not, this is a possible causes. Also, what about the oxygen sensor? This too can be an issue. The TPS and MAP sensor are also very important inputs to the computer so these need to be checked as well. Here is how to diagnoses the problem. Start by checking engine vacuum when the engine runs good and compare the reading to when the engine is acting up and see if there is a significant difference. If so, we have a bae engine mechanical issue that needs to be addressed. If not, then see if the engine runs any better on starting fluid when this happens. If both of these tests passes, then the problem will be related to the ignition system. Let me know!

Customer: replied 1 year ago.
I will have them check it but brand new distributor and new cap and rotor button all new also new sensors and new ignition and keys. This why we don't understand what is wrong with it it also had a new fuel pump last year
Expert:  Amedee replied 1 year ago.
Keep in mind, just because the fuel pump is fairly new does not mean it is good. I have seen brand new parts go bad right after installing them. In addition, there are other factors that can cause low fuel pressure as well so be sure to get the fuel pressure readings WHEN this problem occurs.
Customer: replied 1 year ago.
Ok as soon As I hear from the shop I will make sure they check it and I will let you know.
Expert:  Amedee replied 1 year ago.
Sounds good
Customer: replied 1 year ago.
The shop said fuel pressure is great when running and also has good fe pressure when it starts missing up they shot eather in it made no difference so they are still going to keep checking it out till we get it right.
Expert:  Amedee replied 1 year ago.

Ok good.. and all of the tune up parts have been replaced? Cap, rotor, plugs and wires?

Customer: replied 1 year ago.
Expert:  Amedee replied 1 year ago.

And the cam and crank sensors have been replaced correct?

Customer: replied 1 year ago.
Sorry my phone died yes sensors are all replaced.
Expert:  Amedee replied 1 year ago.

Were the oxygen sensors replaced?

Customer: replied 1 year ago.
Expert:  Amedee replied 1 year ago.

Ok good.. and was the PCM replaced?

Customer: replied 1 year ago.
With a used one and it was flash as well but we are thinking about getting a new one because both do the same thing.
Expert:  Amedee replied 1 year ago.

I suspect that is the route you should go provided everything else checks out good or has been replaced up to this point.
