    2000 LeSabre, car shuts off on interstate at 70 miles an hour or at lower speeds when driving,click to neutral and restarts while coasting, then runs fine for awhile,maybe an hour or two days or ten minutes. went to GM mechanics they diagnosed for 3 days with no luck,told the fuel pressure was 42-43 sometimes 40 psi.Fuel pressure regulator????Fuel control relay??? Fuel filter??? or wiring to relay,short to frame???

2002 dodge ram 1500 convent van keeps sputtering out like its not getting fuel, just put in new fuel pump and still doing it

What is litre size of engine? If you suspect a fuel issue, the first thing, you use a gage and check proper fuel pressure, before you replace anything. How long since overall tune-up? Any applicable trouble codes?
Does the vehicle stall at idle or going down the highway? If it stalls at idle, check and clean throttle body and idle air system, see if it helps.
If it stalls going down the highway, I usually check for a blockage of some kind, fuel or exhaust?
If you lose cam or crank sensor it will kill it. You need to do some testing in order to narrow it down. Don't replace everything.

Chevrolet Cavalier 2004 quits running while driving down the highway.

need to check fuel pressure, not just listen for pump to run, also check reading on coolant temp sensor, but sounds like fuel pump /filter issue. just because you hear pump run doesnt mean its putting our right amount of pressure. also check for plugged catylic convertor

Car just died on the highway, oil light came on but the oil level was fine, and it will try to start but wont.

it is hard to come up with a solution using your brief description, but since the oil level is good it sounds like and oil pressure issue. there are many causes of oil pressure issues, the best solution is to get the car to a shop.

I have a 2002 grand prix 3.8l I've just changed the fuel filter checked the wiring and fuses. my thought is a fuel pump. driving along on the highway about 100kms or more things seem quite normal,...

could be its failing to hold and pump the required pressure the motor needs to keep it running smoothly, but if you check this link, and go down to the part about your engine just stalls while driving, it tells you about the crank pos sensor and the ignition itself
