We have an intermittent problem that causes the truck to stop without warning. Usually it happens in hot weather, regardless if we are on a long trip or just driving around town. At one point on a long trip from Texas to NC it shut off in Monroe,Louisiana . We had it diagnosed by 3 different local mechanics who could find nothing because they said they needed to locate the problem as it happened. Of course the problem did not happen again for them and it was over 1 year till it happened again. Fuel or electronic, we r not sure.

I took the rubber piece off, blew in it to see if obstructed, checked the resevoir and made sure it was full. When you turn on the windshield wipers you can see the fluid puddled up like a drinking fountain coming out but it doesnt squirt out onto the windshield. Help!!!
