Message crank but won't re-start. After about 10 mins. of waiting and doing nothing, I'll try again, and it starts, runs fine...for about 10 more minutes of driving, then it does it again. Note: I said Driving, not idling. It will idle forever & smooth. Problem only happens under load. History: It happened once, then didn't happen again for months..then happened again, etc. Now, as I said, it is failing after only 10min. I'm thinking fuel pump, but unfortunately, when it fails, I'm on the road and can't pick my spot to pull over to hook up a gauge. Can't make it fail in the driveway, it idles forever. I have new:fuel filter, fpr,injectors(no plenum leaks),maf,iacv. Also, this last time it failed, when I was cranking it, it started to drag like a low battery, I stopped for a second, then tried again and it cranked real fast like the battery was fine. It still didn't start.
I'm thinking a failing fuel pump is drawing extra current in it's overheated state(draging starter). After waiting 10min for the fuel pump to cool down, it works again. Sorry for the lengthy post, really need help.
