97 ford explorer 5.0 liter drive abilty prolbems

Idles fine, then when in drive it shudders and stops. Runs very rough. Some
days it will clear up and runs fine for so long 1 day 2 days then this
prolbem crops up again.
Fuel pressure WHILE having this prolbem was 31 psi. Any thoughts.

It's a long-shot but I just had a problem with my '97 4.0 OHV that, as far
as I can tell, was a dirty connection on the crankcase position sensor.
Mine was a starting problem but I imagine it could cause other problems as
well. It'll only take a minute to pull it off, spray it with some brake
cleaner or WD-40, and stick it back on.

Other than that I think I would check the vacuum hoses and connections and
clean the MAF, check the air cleaner etc. But you probably already did
that, huh?

Torq converter stays locked up ????????

I do not know, it has been so long since I have checked a torque converter
I hardly remenber how.
I remenber accelatoring with the brakes on to check the torque convertor.
Your thought was the torque convertor is locked up and killing the engine
whrn it is shifted into gear.
