Car looks really good tho !!
Are you sure it's not the fuel gone stagnant (spelling), or the car runnin out of fuel ??
This happened to mine 2 days ago, as soon as I got to 5 psi or more the car would jus start missing !!

Luckily I got a fuel pressure gauge & could see the pressure drop. Perished hose feeding the pump from the tank was the culprit. 10 mins later all was sweet again !!
Hope you get it sorted fella !!
