So tonite, while I was driving at about 75 mph, my car started losing power going up a hill. When I pulled over to the shoulder and pulled to a full stop, the oil lite and the battery lite came on, and it just stopped. I turned the car off, put my hazards on, and just let it sit for about 20 minutes. The car started up and ran like nothing for about 15 minutes, then it happened again. This happened about five times til I got to where I had to be. I let the car sit for about 45 minutes, it rode fine for about 30 minutes, and then the same thing. Now I was trying to make it home with my son, so I just kept sitting and waiting and then starting it up, but I was sitting for shorter intervals, so it would stay running strong for shorter intervals. The last time that it happened before I just left the car, it wouldn't even start for about 15 minutes. Then it started and it was fine, but I just parked it in a parking lot for the nite, and I will go back tomorrow to pick it up. What could this be? It happened once before, and we thought it was bad gas, so we stopped using that gas station. Now it happened again from a different gas station. HELP, PLEASE.

Is the service engine light on? If so I would have someone check and see what codes are stored? They do this for free at places like autozone. Then repost and maybe someone can help you out.

Without knowing if the service engine light is on or if there are any codes I would only be guessing, but sounds like maybe you have a plugged fuel filter or a fuel pump that may be starting to fail? But there are several variables here so repost and let us know if the service engine light is on and if so post what codes they tell you are stored.

It could be a number of things. Losing power could be a semi-plugged fuel filter, not getting enough pressure to the engine, also the feul pump it self maybe lagging, also if the temp sensor is wonky or if your car is over heating diving up hill and 75mph, it will cut power automatically to save you from blowing the motor, its a self kill switch. Also the alternator could be not charging the battery enough. If you have a bad battery, the car simply doesn't get enough power to register information properly to the computer, this will cause sensors to go off or cause other item to malfunctions cause power will go to the closest route if only a littler battery juice is available. Also PSV valve and air filter could be the culperate.
