Have you checked the fluid with the engine hot, idling in park, on a level surface? What was the level? What was the color when you put it on a white paper towel? Does it smell burnt? Have you pulled any diagnostic trouble codes? Have you checked the wiring harness(es) for loose connections, wear points or potential shorts?

thank you for responding
i have looked at the trannsmition fluid level and it was on the perfect line it did not smell burnt but i will have to look at conections but highly unlikely cause we had went through the motor and wires a little while ago but i will check anyway

Codes?
Short of any trouble codes, I would start leaning towards a pump and or torque converter problem, like my F250 has. When the fluid is cold, it's thicker and builds pressure more easily, but once it warms up and thins out a bit, the worn pump and/or TC can't push it to the pressures it needs to have. That, or you have some valve body or solenoid issues (seals and such), that respond to the same fluid temperature differences.

drain pan, replace filter with a ford filter, drain convertor, use quality fluid.
this is where you should start.

I absolutely agree with changing the fluid and filter!!! DON'T HAVE IT BACK FLUSHED!!!!
Just do it the old-fashioned way, drop the pan, replace the filter, drain the converter, and add MERCON V synthetic fluid, you will have about $75 bucks in this, and I think you will be OK......
