0X66 won't re crank

2000 250 OX66. tons of hours, VERY well maintained. New cranking batteries, spark plugs and fuel pump and water seperator. Cranks OK, runs good but once you stop and try to re start it is a no go. Bulb is hard but just doesn't seem like it is getting fuel. I give

it would be simple to check for spark when it will not start.
then you would know to chase a fuel issue if the spark is all good.

too much fuel or too little could be a problem
it would be good to know if the rail pressure is in spec when this happens also.
have you checked the fuel cooler to make sure it is clear and cooling?

Spark is good, other two items will be checked. Thanks
