Why does engine stop running after half hour of running, and after sitting for about 15 minutes will start back up?


Does it quit smoothly but suddenly? Or does it sputter then stop?
It could be that the fuel cap has a defect that no longer allows air to enter the tank, thus causing a large pressure difference that the pump can no longer overcome. After sitting a while, the tank "equalizes" and the pump can resume its normal pressurization of the fuel system,

Engine stalls on highway starts after 15 min


Sounds like the same problem I have been having with my 2002 Sedona for
the past 6 or 8 months. It would run OK for several days, weeks, or months,
then just quit. If I let it set for 10 to 20 minutes, it would restart and run fine
for at least the rest of that day. About 2 weeks ago, I was fortunate that it happened when someone was with me, so I was able to determine that it
was not getting any spark. Since then the problem has gotten worse and
more frequent - it was happening almost every day and would take over
1/2 an hour before it would start again. This morning was the last straw.
I drove for about 4 miles and it quit. Took 1 hour and 10 minutes before it
would restart. Drove another 2 miles and did it again. This time it took
1 hour 35 minutes before restart. After 1 more mile, it quit again. Took 2
hours, this time. Made it another mile and BAM! - did it again.
My bro towed me home. I determined that it is most likely NOT the crankshaft position sensor, because 99% of the time they either work,
or they don't. Very rarely does it cause in intermittant problem. The most
likely suspect is the engine computer. That was always a likely culpret
when I worked on GM cars. Today I installed a $50 junk yard engine control computer. I am crossing my fingers!
I will know on Thursday, as I have a 50 mile trip to make.
I will post again on Thursday, to let you all know.

This sounds like the electronics warming up.

The behavior of transistors varies greatly with temperature. The circuitry around them is designed to compensate for that, so that the behavior of the entire circuit is reasonably stable over the range of temperatures it is expected to encounter in normal operation.

As transistors age, their behavior can shift such that, when they are either quite warm, or quite cold, their parameters are too far off for the circuitry to effectively compensate.

The most frequent result of this in cars is for the device with the faltering components in it to fail completely at some point during the warm up phase, which, of course, is what you are experiencing.

If there is a separate electronic device that is responsible for the ignition (like the ignition module inside the distributor of a GM HEI ignition), I would suspect that first, followed by the engine's Electronic Control Module.

My car runs for about half an hour then it quits.....after about 15-20 minutes it will start again but then only runs for about 10 minutes.....need to know why


I had this happen once in a Ford. With mine, there were particules in the fuel from bad gas and it would clog the fuel screen on the pump. After not running for a while all the particles would fall off the screen and back into the fuel until I started it and they sucked back up. I dont know if this your problem but it sounds like what happened to me. It might be a place to start checking.

I'd be tempted to have fuel pressure checked, if at all possible, when it quits. If nothing else, carry a can of quickstart with you, and when it quits, remove air intake at throttle body inlet, and open throttle plate and give a good squirt of quick start, then try to start it. If it starts for a second or 2, then you know you have spark, but no fuel. I've seen fuel pumps work good while cool, and cut -out when it gets hot. Then sit and let pump cool off for 20 minutes or so, then pump up to pressure again and away we go, until it gets hot again. You might also find if you park in the shade, you'll get further, or even on a full tank. Another good idea would be to change fuel filter in case fuel pump is working too hard pushing fuel through a plugged filter, and causing low fuel pressure.

THE CAM SHAFT SENSOR IS GOING BAD. WE SEE THIS ALL THE TIME, YOU WILL NEED TO REPLACE IT. IT WILL BE LOCATED ON THE FRONT OF THE VALVE COVER OR THE PASS SIDE REAR OF THE COVER. IT IS ONLY HELD IN BY ONE BOLT SO YOU SHOULD HAVE NO TROUBLE REPLACING IT.

Try cleaning the fuel pump filter. Under the seat behind the driver lift the carpet and you will find a round cover with six screws remove the cover. The fuel pump is directly below unscrew the retaining round plate and remove the pump. At the base of the pump is a small filter if it is covered in black muck that's your problem. clean and replace. job takes about 10 mins good luck. please let me know how you got on!

1991 Plymouth Acclaim stalls


One of the more common problems with the 2.5L & 2.2L engines that suffered the symptoms your describing, such as, starts & runs good, then at any given time would just quit, not start, but after sitting a while, or by the time the mechanic gets to it, it starts right up, or you sit on the side of the road for 20 min. or half hour then away it goes for a while longer, then quits again down the road. There is a pick-up plate under the distributor cap & rotor, with the wiring plug coming from it. 90% of the time, it's defective, and cuts out especially, but not limited to, more often when weather is hot.
