car won't accelerate more than 10-15mph

It sounds like you are in fail-safe (limp) mode. You'll have to run diagnostics to find the cause. Something is changing when truck is running under load, versus sitting at idle. You can pull codes, it will give you some clues. If it's timing related, that may explain why it idles fine but goes into limp mode under load.
