My car will stop accelerating if I drive it for more than an hour or two.

Hi,

Does the engine stall? Is the check engine light staying on when the engine is running? Also, have you had the computer system scanned for diagnostic trouble codes?

Here is a video that shows how to scan the CAN bus system. CAN stands for computer area network. By doing this, all computers / modules are checked. There should be a code showing a fault.

Let me know.
