We finally took the truck to the shop and got it fixed. Turned out to be some sort of solenoid that had a glue bond that had come apart and was not operating all the time. It would vibrate back and forth and cause the erratic problem. The starting seems to be improved also. It is not perfect, but it starts much closer to normal and it's not going to ruin a starter anymore.
Thanks for all the tips!
