It could be a partially blocked fuel filter that fills with sediment after it's run a while then the sediment settles back after the engine is off. Another option would be heat failure in one of the electronic devices such as an ICM or other electronic device.
what is the problem if a Chevy diesil engine start and run 30 minuits died and start right up again
One common problems is a plugged catalytic converter, if the engine starts fine and then starts to stall or feel like it does not have any power after running for a while it could be the catalytic converter.. the engine starts loosing power because the exhaust has nowhere to go (the catalytic converter is partially or totally plugged) Compression starts to go down causing the engine to stall or die. If you leave the car alone for a while the pressure in the engine goes out slowly thru the catalytic converter leaving the car ready to start again for a few minutes but it will shut down again.
replace your crank sensor....or when it dies dump cold water on it to see if it starts again
i have replaced the plugs and wires and my service engine light comes again in 2004 land rover discovery
I would change your fuel filter
try replacing the ignition coil. after it hots, it starts breaking down and will not fire again until it cools off
Check out your fuel filter it sounds as if it is clogged and after sitting for a few minutes the debris falls away and lets it start and run until it becomes clogged again.
You need to give more information on engine before anyone can assist you with this!
change the fuel filter you have two
check fuel pump fuel pump
A plugged up fuel filter, a faulty fuel pump, more info like the year, make and model would help.
