3.3 V6/auto 1998

The truck is not able to accelerate and the engine cuts in and out like someone is turning the ignition on and off really fast, worse as I give it more power , or more power is required.

#1 problem only occurs when the truck is warmed up and gets worse the hotter the engine gets

#2 I had a check engine light for random cylinder misfires code 0701

#3 did the haynes test on the coil secondary and primary and the power transformer, all checked out, this test was done while the engine was hot.

Ideas?
