This could be due to several factors such as faulty sensors, clogged fuel injectors, vacuum leaks, or worn spark plugs. I recommend having a mechanic run a diagnostic to pinpoint the exact cause of the rough running when warm.

Why does my 98 astrovan run good cold and then lose power after warm up?

This could be due to a variety of issues, such as a failing fuel pump, clogged fuel filter, or a problem with the engine's sensors. When the engine is cold, these problems may not be as prominent, but as it warms up, they can become more noticeable and cause a loss of power. It's best to have a mechanic perform a diagnostic to pinpoint the exact cause.

They also use winter-blend diesel fuel that has additives to prevent gelling in low temperatures. Additionally, drivers are trained to drive cautiously and be prepared for icy road conditions.
