93 Ramcharger suddenly died

I need some help with computer controlled stuff...
My 93 Ramcharger suddenly died while we were driving. Putting along at 45mph and all the sudden like the key was turned off, it died. no speedo either, but my temp and alt gauge still worked. Oil press did not since it was not running. I did some checks after getting it parked, and tried to pull codes with the key trick. nothing at all. no blinks, no engine light at all either. I do know that it did have codes b/c it did have a faulty O2 sensor the week prior. Which I replaced.

It will crank over. No spark. The rotor turns. I am thinking it may be the computer from what I have been reading. No speedo control and sudden engine quitting leads to the CPU. Am I in the right direction to order a new one? Thanks
