This could be a shift solenoid, or you have a gear range sensor going out, can I ask when you put the truck in reverse does the backup lights go on? If not, I would start by checking the fuses which. This guide can help you, be sure to have the key on when checking:

If the fuses are okay and the reverse lights are not going on I would replace the gear range sensor, here is how in the images below. Check out the images (below). Please let us know what you find.

They don’t come on, but I think they just don’t work at all. it’s only not engaging reverse sometimes.

If when the transmission goes into reverse if the reverse light work when this happens then you have a bad gear range sensor. Please note the operation to confirm.
