99-s-10 v6 won't start

we tried every thing, replace coil,crake sencer, fuel pressure is up to sixty, once in awhile it runs for few sec but stops.was going down the road when the engine just stopped running like if you turned the key off???????????

didnt run rough at all? 2.2 or a 2.8?

check your connections on everything.

everything is connected, looked all over engine, underneath, etc

looks like my truck has the same problem, driving on the high way and suddenly stalled, i took to the dealers and they say the engine is over heated. I need a new one. my truck is 99 2.2L only 100k miles on it and it's pissing me off.
