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
