Hello

CAUTION! DO NOT MAKE ANY SPARKS WHILE THE FUEL SYSTEM IS OPEN, GASOLINE FUMES CATCH FIRE VERY EASILY

Check and make sure the Power Wire going to the Electric pump is Heavy Gage, if it is too light in gauge it may be getting hot and not supplying adequate voltage at the pump.

You can check this by putting a Digital Volt meter probe on the power wire at the pump and turn the pump on and see how the Voltage stays, If the engine is running it should be around 14.0 volts steady and not drop as the pump runs, if not running put a battery charger on the battery and charge it at the 40 Amps rate, a trickle charger or battery tender probably will not put out enough amperage to keep up the battery fully charged under the load of the Electric Pump.

Also check that the suction screen, hoses and filters in front of the fuel pump to see that they are not collapsing out of the tank or in the tank.

Make sure all filters are clean, i.e., they should be fairly NEW.

Hope This Helps

P.S.

If the charging system is not putting out enough amperage this too could lead to a poor running engine since the ignition system is starving for power too.
