Sounds like it could be your starter or your fuel pump. Both have similar traits when they're on their way out.

Replace the temperature sending unit/sensor. It tells the computer to place the engine into cold start mode.

There are still many possibilities. The internal combustion engine is a complex mechanism. The timing could be off. All spark plugs must be firing. They must fire at exactly top dead center. The timing chain/belt must be in good working order, not worn or stretched. The cam shaft must not be worn out so the valves open and close correctly. the valve lifters must be working properly. the cylinder heads must have the same correct compression. A different compression indicates bad valves or head gasket. Piston rings must not be worn out or they will not provide adequate compression. the oil pump must circulate the oil to lubricate everything, and provide fluid for hydraulic lifters. Oil and filters must be clean and the correct type for engine and climate.
