Hello Khan,
It looks like your having some fun sorting out your car,
Don't get stuck on the fuel but defiantly eliminate it as a problem.
Also it may be a electrical problem,
Some of the one’s I have encountered are and act the same,
Coil for the plugs would heat up and cut out like no fuel, fix was a new coil and
a resistor wire or ballast resistor rated at approx 1.4 ohms.
Electrical short or break, recently I had a reverse lockout switch on a Hotrod give me problems would cut out when driving.
All easy fixes once you find it!
