1987 volvo740turbo starts right up,but as it drives a bit, it doesn't seem to get fuel enough to keep trans engaged esp. when it gets warm...the engine just, dies. it will start again, but poops out after 50-100yards. at best, and when the car's still cold, i must stand hard on the gas to make it shift. what's up with that ?
could it be a fuel regulator ?
When was the fuel filter last changed? I'd start there.
