1991 4cyl camry auto trans,engine cuts OUT while driving
I start the car and warm it up. However, while driving the car shuts down. I try to re-start it but it just cranks. Were finding that if the cars sits for a few hours, we are able to re-start it, like nothing is wrong.
If you drive it again for about 15-20 minutes the same thing happens.
Could it be the EFI water senor for engine control or Idle Air Control Valve?

Replace the control moddule .its under the hood along the fire wall . i had a ford pickup would start fine . untill the moddule would get hot and shut off the motor it would crank and crank but if i let it sit and cool off it would start right up as if nothing was worng .let me know if you find the module . you might need to by a clymers book at a auto store and it'll tell everything there is to know about your car and were and how to find and replace everything

There are a few thing's that could make it shut down while driving !
The ASD relay , auto shut down relay, .crankshaft position sensor ,ignition module . any engine data sensor if on the 5volt reference circuit ! Does it start right back up ? When does it do this ,when the engine is fully warmed up ? Is the check engine light on ?
one thing ive warned my friends to never do and that is to never have your trans flushed cause you may have new fluids but what about the trans filter its old and iots there for that reason to keep dirt and metal; shavings from the bands so try having your oil and filter in the transmission replaced , pull your trans dip stick and on a white piece of paper put a drop of trans oil that you have in your trans at that very moment it should be redish pink but if its brown and smells really bad then the problem is in the oil and filter . change it before u have to replace the whole trans
the torque convertor is locking up,There is a plastic wire harness on top the transmission,Unplug it from the transmission and your troubles will cease, If you want it repaired and transmission shop can do it,or you can drive it for ever unplugged
I'd go for a free code scan first at one of the major auto parts stores, then you have an idea at least where to concentrate your efforts. Saves money in the long run, and if you prefer, write them down, and get back to us for some help.
power light flashing means trans sowas he able to retrieve any codes?check harness connections for trans in engine compartment,also wiggle engine harness in area between tran and engine bad groundf loose connection sounds like cause
give the engine a minute or two to cool down before turning it off. This cool down period allows oil to circulate and cool down the bearings in the turbo. If you shut off the engine immediately after hard driving, the oil can gum up around the hot bearings and create problems down the road.
Hope this helps
i had the same problem after spending $500.00 for toyota to look at it they didnt fix it and suggested i it was the auto trans and i should get it overhauled costing thousands. i didnt believe them and started to do some of my own research into the problem. the coolant temp sensor at the rear of the intake manifold tells the ecu when the engine is at correct operating temp then allows the auto trans shift into overdrive. to rule out any problems with the auto trans i disconnected the plug to the temp sensor and went for a drive when the engine was cold and it shifted straight away into overdrive no problems. you can't leave this disconnected because the engine is hard to start when cold as the temp sensor also tells the ecu that it is cold and allows the cold start injector to inject more fuel into the engine on cold start up.to overcome this i cut the wire to the sensor plug and installed a switch which i installed into the centre console.now i start the car flick the swith use overdrive then swith back to normal after car has warmed up . engine fault light appers on dash when switched on but doesnt matter. i have had this modification for 2 years now no problems.
