99' 5.2 4x4 won' start

Went to work, came home, went out to a friends, 45 minutes later...won't start. I have four friends w/ram PU's, and all have had to replace the fuel pump, one twice! Does not seem logical that it would run, idle, then not start. Gut tells me its an electrical prob. Any Ideas?
It has spark, but it's been bad weather and havn't checked for fuel. Is this fuel pump an issue with all Rams??

get a pressure guage a check the fuel pressure, it should be at least 40 psi for it to run. the test port is a shrader valve on top of the fuel rail. it will have a black cap on it. if it less than 40 psi, i would advise replacing the fuel pump assembly.
