Very Strange. Car Shut Down Twice at High RPM

pits200 · 12-09-2011, 07:55 AM

I do a lot of highway traveling and every once in awhile when traffic is open and no cops, I like to do a small 65-90 romp to help with my boredom.

Now on the way out to my destination, when the car got up to about 6k rpms, the car just shut down. I still had full electrical power, steering was fine and so were the brakes. The engine just simply turned off. So I coast off the road with only the standard check engine light on. I turn the car off and then turn it back on and sure enough, no check engine light, and the car fired up without a hiccup. I pulled out my laptop and there were no codes showing up.

Now on my way back from work yesterday, once again when traffic was open, I decided to try the same thing. Now mind you, earlier in the trip after the first incident, I did other runs similar to the one that turned the engine off. But once again, the same thing happened, except this time when I tried cranking it over, it took 3 times.

Drove the car home the last 100 miles and not one issue. Pulled out the laptop to check and did a log and everything seemed perfect.

I have full bolt ons with 93 octane and stage 3 rev 2.5 maps.

ANY HELP and yes I technically still have a warranty and this is pretty much the first major problem I've had with the car.

similar issues were normally related to HPFP failure. Turn Can clear OFF and Check the codes.

Oh really, I get no long cranks, no limp mode and no issues any other time.

I've been racking my brain with what can be so intermittent and I can't think of anything else.

I thought hpfp would be long cranks, rough idle and limp mode.

Either way, thanks for the input.

Like Enrita suggested you need to see what codes are popping up. I had a simalar issue, but mine was at low RPM's it would just shutoff/stall. Drove from Tampa to Orlando and as soon as I got off the highway and stopped at stop light the car shutoff/stalled. I was getting codes 2AAF, 29F2, and 29F3 which ended up being a faulty fuel temperature/pressure sensor.

I had one HPFP go on me and I never had one long crank with it. When that one went on me, I pulled my tune and cleared everything. Driving around normally, nothing would happen...no problems. Putting load on it exactly like you mentioned (60-90) and it would trigger it on the spot. My SA said the pump was sucking in pure air and that the seals were shot. I would remove the tune, go WOT under load and see what happens.
