    Check fuel system;

    Fuel pressure - could be the problem. Make fuel pressure test with mechanic assistance

    Fuel pump faulty - check the voltage

    Check pressure regulator - disconnect the fuel return line, is fuel being returned during low pressure?

    Dirt in the fuel tank - clean the tank

    Dirt in the fuel lines - clean the lines

    Clogged fuel filter - replace it with new fuel filter
