97 Ram Shakes Then Stalls When Braking Before It Warms Up

[Ordy]

This doesn't happen in the summer above 80 degrees but....... If I don't let the truck warm up it boggs down when I start to drive. Then when I brake it shakes then stalls. Heavy pressure on the brake pedal when this happens. Like the brake pedal doesn't want to move. I really have to stand on it to get it to brake, then shakes and stalls. Once the truck warms up it's fine. Any ideas?

I should also say it Idles fine. If I let off the brake before it stalls it also goes right back to idling fine.

The “heavy pressure on the brake pedal” kind of points to a vacuum leak in the brake booster.

Might try disconnecting the vacuum line from the booster, plug it, and see if you still get the stalling.
