Iwould start by checking all your fuses, then make sure the timing chain is spinning and did not pop, next is to check the control module this is what controls the spark and injector pluse, many part stores can test it for pump is ok  but my injeters is not pulsing - e402891.jpg

Runs good, after 30 mins stalls no injector pulse and hard to start.after 10-15 mins starts again, spark OK. changed fuel pump,distributor. Same

run the fault codes and check for problem ECM
There is an electronic component failure in the injector circuit that when over heats , shuts that injector circuit down
try replacing the ECM with a known good unit

Take it to the dealer if you can't afford it buy parts then you to worry about labor. No second guessing your car is your life that brings you to work and everywhere you treat it like dirt it's going treat you like dirt.

The engine power pulses at higher RPM and sometimes the engine stalls after starting. The problem is intermittent and seems like it might be fuel pump related.

Your going to receive answers about electronic issues and spark plug wires and dirty injectors, but I would start with a fuel pressure test because of the way you worded your problem, (OK, at idle, but when a demand of fuel needed, pulsing) Probably a fuel pump problem if dry gas can't clear it up.

Car starts and cuts out after 2 to 3 seconds. fuel

When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.
