It could stall if you use the rear brake while going downhill. Is this the case?
Check for leaks in the intake manifold or a poor fuel pressure situation.
I had that issue with my Cavalier and it turned out to be a fuel pump problem. I would check with your local mechanic.
with me it was the o2 censer
Had a 1995 Cavalier with a similar problem. It was some type of solenoid on the transmission (automatic). Cost about $500 to replace at the dealer.
A Ford Transit may stall when going downhill due to several factors, such as an issue with the fuel system, like a clogged fuel filter or failing fuel pump, which can lead to inadequate fuel delivery. Additionally, problems with the vehicle's electrical system, like a weak battery or faulty alternator, can cause power loss during deceleration. Lastly, if the engine's computer detects a problem, it may trigger a stall to protect the engine. Regular maintenance and diagnostics can help identify and resolve these issues.
It needs a tune-up.
Oxygen sensor
There could be a couple causes . The first would be the oxygen censor isn't working properly and the other is the coil pack is probably going out.
it sounds like ur clutch went out in it.
Your timing could be off.
No, it will just stall and cease to run.
