I was cruising down the highway approaching my exit when i decided to accelerate a little to get ahead of a semi that wouldnt let me over. press the pedal a little, accelerate for a second, then my engine shuddered and just died. would not restart. pull on to the berm trying to get her to turn over again and all she does is shudder violently. call for a tow, truck comes, drops me off at the house, figured i'd give it one last try. Who knows, maybe the bumpy ride shook some dirt loose. turn the ignition and success! she comes to life, leading me to believe its just the gas. thoughts? oh, no CEL btw

 

i dont really know **** but maybe your alternator/battery crapped out and recharged on the way home

 

well if it was the battery the starter wouldnt turn when i tried to restart it right after

 

how would it recharge on the way home?? car wasnt running lol (i dnt thinkk tht the car was pluged in to the tow truck)

 

Coil? i know when coils go bad sometime when they get hot they quit, once they cool off then they are good to go

 

yeaaaaaaa

 

haha sry thought it was common sense

 

^^^^ what kind of bike you ride?

 

YZ 250. You ride?

 

used to up until 3 years ago when i broke my back. you race? i'm so jacking this thread

 

this does sound like a ignition coil possibly crank shaft position sensor problem. I have seen CKP and CMP sensors go bad when they reach a certain temperature.


Not to agree with Brickloaf, but a battery that is run down by a bad alternator/other charging issue but is otherwise ok, will recover some voltage after sitting/cooling down for a little while.

 

i wanted to get into racing but i didnt have the money for it... its expensive. my whole family rides and we go up north in michigan and do hardcore trail riding on trails that are barley wide enough for handle bars haha. its alot of fun tho. what kinda bike did u ride?

 

i had one of those along with the camshaft sensor go bad on my jeep when i had it but when it would shut off it wouldn't shudder or anything it just died and it would eventually restart but i would take a couple trys

 

Oh boy i started on rm80's then moved up to yz125's. Ive probably had about 6 of each. used to get a new one every year. Raced 125A "pro class". Do you live in upper mich? ever hear of redbud?

Sounds more like a coil to me

 

i agree cuz when my sensor's went bad i had no shudder before it died and u will get a cel idk if this is true but i was told u can drive with one of the 2 sensors bad (crank shaft and camshaft) and it wont shut off but when both go bad it will shut off

 

Could be a fuel pump. They can be fun like that. Dies on you then starts up again later. Hope it's not though. They can be pricey

 

moved to PM's to end thread jack

 

hmm. i'll drive it for now i guess. when i restarted i had no CEL and ran just fine.
