I think that it is electrical......

I have a friend who has a 90 Dodge Grand Caravan (8-91build), 3.3 V6,DIS. This van will start cold and run fine for about 5 to 30 minutes. Then from diagnosis he has found that it loses total voltage to the coil pack. He tested the terminals on the volatge pack and found that the B+ terminal had no voltage. After sitting for a few hours if will have voltage and the van will start.

Thanks to anyone who can help

have you checked the ECU under the hood next too the relay box. it was an issue on my 96 grand caravan when i had the same issue and the it quit starting completely. it was 400.00 bucks but i know the local shop in town ran a diag on mine for 50 bucks and was willing to put that towards any repair i did with them. If that is not it the diag should tell you what it is. good luck
