The problem progressed, though, until it began to stall out. It would> slow down to an absolute crawl, regardless of the gas pedal position,> then stall. It would then generally restart, but would stall again a> few times. I noticed that if the engine were off for a minute or two,> it would start right back up. Eventually, I was stranded a couple> blocks from home, unable to get it started again. I looked under the> hood for any obvious signs of distress, checked fluids, looked for> leaks. About ten minutes later, I decided to try to start it again,> and it started right up- only to crawl that last two blocks, stalling> regularly.>

Couple things: the engine doesn't run hot- the needle stayed right in> the center through all of this. Also, the loss of power was not> sputtering, like when one cyllinder isn't firing- it was always smooth,> even while crawling. Fuel filter is a year old, looked new at last oil> change, maybe 500 miles ago. Also, the following day, I couldn't> replicate the symptom. At least, not by running the car for 25> minutes.>

So, it seems temperature-related­. Fuel pump relay? Fuel pressure> regulator? Fuel pump? How can I tell? And where is the fuel pump> relay anyway?>

Does anyone else feel that it might be a fuel problem? Any experiences> with temperature-related­ power loss? Or replacing the fuel pressure> regulator? Or with this crank angle sensor causing my symptoms?>

Thanks again.>
