I think what you have going on here is a failing electric fuel pump, this is what they do when they are worn out, it is a rotary pump and the rotor sticks due to worn bearings. To confirm this get a can of spray starting fluid from any auto parts store, next time it won't start spray it into the air intake hose to the engine, if it fires right up you have a bad pump. The fuel pump is located inside the fuel tank, remember to also replace the fuel filter when the pump is replaced. Also check the connector to the fuel pump cutoff safety switch for signs of melting, replace the switch and connector as needed, this is caused by a defective fuel pump drawing excessive current.

check your sparkplug wireing there may be a break in one of the wires also check your spark plugs one mayh be loose

ABS light come on when this happens ?

the noise can be from the fan next to the compressor or the fan in the freezer.

THESE PROBLEMS ARE FROM THE FUEL PUMP AND THE SENDER, IT COMES AS A MODULE ASSEMBLY, IT IS INSIDE THE FUEL TANK

check your air flow mass air flow sensor

this problem I find in alot of 3.4 ltre grand-ams and that is the wiring go to the intake air temp sensor is broken at the connector. the wire will look good but in the insulation it will be broken. just give each wire a tug, if the wire pulls out then that is the broken one.
