I'm sorry to hear that you're having an issue. Hopefully it's a simple fix.

In nearly every case of a vehicle cutting out while driving, there is ultimately a connection issue between the chip and the PCM. It could be from over-cleaning or under-cleaning the PCM connector causing an issue, or there could be a vibration that causes the chip to wiggle a little and lose contact.

I would suggest:

• Disconnect the PCM Connector to kill power to the PCM
• Removing the parking brake assembly
• Remove the chip from the PCM
• Take a piece of Scotch Brite and lightly buff the contacts on both sides
• Wipe contacts with alcohol and a paper towel
• Blow out the connector on the chip just to make sure there's no silicone in there
• Reinstall the chip in the PCM
• Rock the exposed part of the chip back and forth slightly (in this case, left and right) to help seat the contacts
• Use vinyl duct tape to fasten the chip to the PCM (this prevents vibration)
• Reattach the parking brake assembly
• Make sure that all cables are routed smoothly and not pinched anywhere
• Reconnect the PCM connector

This should most likely clear up any issue you are having with the stalling.
