Hi Dan, My name is***** will be glad to help.Is it throwing any engine or transmission codes when this happens? If so what codes are you getting?
Thanks for the info. It sounds like a possible clutch slipping or a loss of throttle or engine speed signal to the ECM. Do you lose throttle response from the fuel pedal when this happens?
Ok then.... Ill opt out. Good luck
