Still no problems
Well I figured I would wait and give some time before posting back for results. After hauling a welding machine on a tag along trailer for a 4 hr round trip and quite a bit of in town driving since, I've had no more problems. The PCM was the problem. "jetsfan67" above suggested purchasing a PCM from an auto parts store and I agree. If it would have given me problems,...that would have been my next step. Good luck to everyone and thanks for this thread.
