Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
This could be awiring issue as things tend to expand when hot and its possible a poor orpartial electrical connection is being pushed apart on one of the major sensorsso check the connection plug and wiring to the following;
Crank position sensor
Cam position sensor
Throttle position sensor
unplug each inturn and use some switch / contact cleaner spray on the pins to ensure its all grease / dirt free
Also worth checking the connections to the fuel pump for the same reason - unplug each in turn and give them a good squirt of switch / contact cleaner - Not WD40
and also unplugand inspect the main power relays and fuses for signs of overheating or corroded terminals - so the ones for the ECU and the fuel pump
And also unplugthe wiring loom connections in the engine bay one at time and inspect for corroded or recessed pins.
If this is all OK then replace the crank sensor
