Rough idle, no rev at all, and shutting off by itself after a minute

[Caffe]

Morning gentlemen.
I want to share within the forum what’s going on with my 2001 boxster, base model and 63k miles.
Hoping experienced folks can chime in and help. Thanks

The following video tells what’s going on right now with the car:

Let me tell you that The car was running just fine before I started with replacing the sparks. Those are the works done so far:

1. Replaced sparks with NDenso. Bosh were previously mounted
2. Go for a spin, about 2 miles and she started misfiring. Barely I was able to return home
3. Reader showed misfiring cylinder 3 an 5
4. Cleared the code and as soon as done it, while the engine was on, it shot down by itself
5. Ordered new sparks Beru, replaced but no luck same behavior . And no fault code or check engine light on
6. Ordered new coils Beru, installed but no luck . No codes or check engine light on
7. Battery disconnected and reconnected several times. No result
8. Battery full charged, 3/4 of gas tank 93 oct, one minute procedure, no luck same behavior and again no lights on or codes

Any advise is appreciated and since the car doesn’t run I cannot get to any shops.
Thanks again in advance.
