While driving today, the engine cutout about 7-8 times. It happened during accelleration, decelleration, up hills and down hills. Tank has just over half a tank. I did notice that the pressure regulator was indicating 6.5 PSI. I had previously adjusted it to 5 PSI. So I have adjusted it to 5 PSI and will monitor the situation.
These picture were taken with the engine warmed up and idling.
Heres a video of the engine idling and the pressure set to 5 psi
