Trying not to get stuck on the road, last week drove x-country to NJ. when we got there the truck "burped" a cpl of times, did not quite quit, but put in in neutral & kept it running, has since done it twice more, and once after putting in the spare CPS. Drove great all the way home.
In all instances when it happened, the truck was not pulling but decelerating/coasting, first time the cruise was on, thought that was the problem at first.
the "burping" actually feels a lot like starting off in third gear instead of first.

any ideas? maybe Torque converter is not down shifting?? also, recently before this happened, I noticed the engine RPM's are higher than normal at idle after warmup, 900 vs usually 700
